PrBoom-Plus 2.5.0.1 released

Changes from v2.4.8.5 to v2.5.0.1

[!] Updated to the latest prboom 2.4.8. (SVN build, revision 2936)
[+] New hardware-mode algorithm for drawing flats into holes left by missing textures, greatly improving compatibility with software mode. This requires a stencil. This revision fixes at least one billion HOMs on various levels which use this software trick. Eternal.wad map28 as example. Old algo will be used with gl_compatibility 1 in cfg. Thanks to GrafZahl.
[+] Experimental cygwin/mingw32 compilation support.
[*] Resolution limitation is removed. Memory usage has decreased as a bonus. 7 mb instead of 8 on map01 @ doom2.wad and 14 mb instead of 18 on map05 @ epic.wad at 640x480.
[*] launcher_enable variable now has three values: "never", "smart" and "always". "Smart" behaviour was default earlier.
[*] Attempt to optimise screen pitch to reduce CPU cache misses in any resolution.
[*] Do precache level with normal demo playback if level_precache 1
[-] Fixed rare crash in FixedDiv introduced in Boom.
[-] Status Bar was affected by light level of the sector on some on-board Intel video cards.
[-] PrBoom will not try to show (with following unexpected exit) the fourth episode menu item for pre-ultimate iwads. Makes sense for doom.wad v1.2, DOOM 1 shareware and DOOM 1 registered. (introduced in 2.4.8.3)
[-] Re-fix vanilla imprecise calculation (vibrations) of the texture coordinates for flats in software renderer.
[-] Fixed wipe in software.
