 Increased number of fractal slots from 4 to 9

Implemented optimized (analytic) calculation of estimated distance for hybrid fractals. Added calculation of analytic DE for benesi, bristorbrot, buffalo, fast_mandelbulb_power2, hypercomplex, mandelbulb2, mandelbulb3, mandelbulb4, quaternion, xenodreambuie
 Added "start iteration" and "stop iteration" numbers on each hybrid formula tab.
 Added selection for distance estimation method (Preferred / Force DeltaDE)
 Added selection for distance estimation function (Preferred / Logarithmic / Linear)
 Added displaying of actual distance estimation method and function
 Added displaying of "wrong distance estimations" below optimization buttons

Added automatic selection of preferred distance estimation function and method for hybrid fractals Added checkboxes to disable constant addition for each fractal formula tab
 Added 'repeat from' setting for hybrid fractal sequence
 Display fractal names on fractal tabs
 Added reset button on each fractal tab to reset fractal parameters
 Added default bailout values for all formulas

Added information box to each formula, where is reference and formula code
Added icons to fractal selection combobox Added settings for Julia mode on each fractal tab to be able to render Julia fractals in boolean mode

Added swapping of fractal tabs  Added many interesting example setting files (at least one for each fractal formula)
 Removed "extended" formulas. It reduced number of parameters used internally in the program (about 600 less). Now processing of animations is much faster.

Added random lights effect (reimplemented from Mandelbulber 1.21 with improvements)
Added buttons for automatic optimization of distance estimation factor Modified user interface for rendering engine (grouped into categories)
 Added support for "sweet spot" rotation (needed for fulldome images)
 Added several coloring algorithms based on orbit traps calculation
 Much faster rendering of DOF (better usage of OpenMP). Enabled OpenMP for DOF effect under Windows.
 Added preliminary pass for DOF effect (much better quality). Now is used focal blur instead of gaussian blur
 Added HDR version of DOF effect
 Enhanced toolbar. Icons are rendered in background process. There is possible to change icons size. Changed way of removing icons.
 Added measurement tool to get pixel 3D position and distance between two indicated points
 Added copy / paste / reset functions for vectors (in context menu for edit fields)
 Added TIFF support
 Improved scaling of 3D cursor
 Added flight animation countdown for start capture
 Optimized initialization of fractal sequence (speeds up rendering)
 Formulas sorted on the list in alphabetical order
 Added support for 4D parameters
 Changed corner assignment for docks. It improves UI on low resolution displays when animation dock is displayed.
 Renamed "Options" tab to "Global parameters"
 Fixed bug: Wrong frame numbers in "Interpolate next keyframes"
 Fixed bug: "Interpolate next keyframes" caused application crashing when right clicked in the white space to the right of the keyframe parameters
 Fixed bug: Found bug in MyGroupBox in slotToggled. It hid all objects also inside widgets. It caused problem with showing them again and could make application hang.
 Fixed bug: Missing creation of "settings" directory at first program start.
 Fixed bug: PNG files weren't saved properly when used special chars in filename under Windows
 Fixed big: mixed slashes and backslashes in filenames under Windows
 Fixed bug: there was problem with saving settings when lastSettingsFile pointed to file which didn't exist. Then in file chooser in filename edit field appeared full file path.
 Fixed bug: reset view function sometimes failed
 Fixed bug: Corrected coloring of translated/rotated objects in boolean mode
 Fixed bug: sometimes calculation of refractions gave negative results. It caused dark spots on image.
 Fixed bug: fixed problems with dividing by zero in DE calculation (rendering sometimes hanged)
 Fixed bug: Camera absolute step mode gave strange step value at application start
 Fixed bug: Default text color in dark skin was unreadable in Info window
 Fixed bug: program crashed when at first program start there was used language different than English
