VBE_RM: EDID: removed semicolons after defined values
VBE_RM: comments to vbe interface functions
VBE_RM: clean example/testing mode selection
VBE_RM: get mode number, their parameters and filter them

in the filtration we want modes to have these flags:
supported in hardware, color mode, graphics mode,
availability of linear frame buffer
VBE_RM: sort filtered modes

currently modes are sorted from the most pixels per line to the least
pixels per line, for modes with the same amount of pixels per line
follows descendant sorting using number of lines and if modes have same
amount of lines then it sorts using bits per pixel
VBE_RM: read EDID from the display to determine mode to be used

the function findModeUsingEDID is not well tested yet due to lack of
hardware
when the function above does not find any usable mode we set first
mode from sorted list of modes
on notebook with Samsung display only Preferred Timing Descriptor
(dtd_md[0]) was available and had resolution (1280x1024) which was not
returned as supported by VBE (Intel Crestline GPU)
VBE_RM: removed unused pointer, corrected indentation, better comment
VBE3.h: updated documentation file attribute
