Optimised the textures of defaultwall with fast preset.

Fix simpleitems transparency in gles2.
Fix a couple of GL errors in gles2 (including some fixed function stuff that could result in segfaults).
Dynamically adjust MTU values with legacy qw clients too.
Added some small sleeps while waiting for downloads (this fixes insanely slow valgrind startups but might make non-valgrind start a smidge slower).
Fix title metadata in the updates system.
Clean up some issues for when WEBCLIENT is not defined.
HAVE_HTTPSV also disables websocket connections, to completely avoid any http strings anywhere, in the hope that it reduces virus scanner false positives.
Fix presets initial option, again.
Writing files to FS_GAMEONLY no longer purges the entire fscache, which should give a speedup in certain situations.
Added some new cvars to control heightmap lightmap generation.
