[imp] Easy one- Change username/password/language text color...

[Kyle Johnson]

I've changed the background/image displayed on my IMP login via edits to
imp/templates/login/login.inc , but now my Username,Password, and Language
prompts are faded into the white background I've chosen!

I'm PHP/HTML crippled, so if someone could tell me where to change these 3
prompts to appear as black text, rather than white, I'll go back to my cave
and not bother this list again. (crossed fingers behind back)

Many thanks-

Kyle
