Search extension from the end of the map name instead of from the start.

[Diordany]

Currently, the map command scans the name for a .bsp extension using strstr(). This works fine for any map that follows the naming style name.bsp, but would break with pre.bspname.bsp because it searches for the first occurence of .bsp from the start.

In the patch, I first search for the . character using Q_strrchr() which searches in reverse from the end of the string. If found, it compares using Q_strcmp() and terminates the string there if the extension was found.

I tested this by invoking the following commands:

map start
disconnect
map start.bsp
disconnect
map death
disconnect
map death.bsp
disconnect
map a.bspdeath
disconnect
map a.bspdeath.bsp

My id1/maps directory in fact has the files for testing purposes:

death.bsp
a.bspdeath.bsp

death.bsp → Death's Taste
