Subject: q3map2/image: also look for images path without extension but with dot in their name
X-Git-Url: https://git.rm.cloudns.org/?a=commitdiff_plain;h=bee71bf6043ec50bb9cc029d7f656920b4df2b2c;p=xonotic%2Fnetradiant.git

q3map2/image: also look for images path without extension but with dot in their name

make sure that if a shader contains path to textures/directory/some.thing
q3map2 also look for textures/directory/some.thing.tga
instead of only looking for textures/directory/some.tga
