Mods menu: improve base and d3xp entries, set d3xp basemod for more mods

the base game entry is now called "Doom 3 (base game)" instead of
"dhewm3", which should be more obvious, and the d3xp entry now reads
"Resurrection Of Evil (d3xp)" instead of just "d3xp", which certainly
is clearer. d3xp now is also always second in the list (if installed)

Added the freshly supported perfected_roe and sikkmodd3xp mods to the
list of mods that need fs_game_base d3xp set, so they can be started
from the menu.

also added an entry for r_gammaInShader to Configuration.md

 - `r_enableDepthCapture` Enable capturing depth buffer to texture. `0`: disable, `1`: enable,  
   `-1`: enable automatically (if soft particles are enabled; the default).   
    This can be used in custom materials with the "_currentDepth" texture.
+- `r_gammaInShader` If set to `1` (the default), gamma and brightness are applied in shaders
+   instead of using hardware gamma. May cause visual glitches with some mods like Sikkmod.
 - `r_useCarmacksReverse` Use Z-Fail ("Carmack's Reverse") when rendering shadows (default `1`)
 - `r_useStencilOpSeparate` Use glStencilOpSeparate() (if available) when rendering shadow (default `1`)
 - `r_scaleMenusTo43` Render full-screen menus in 4:3 by adding black bars on the left/right if necessary (default `1`)
