attack modes description missing

[M@LIK]

@skalderis:: You fooled me more than you fooled yourself!

oclHashcat-lite doesn't have any attack modes other than brute-forcing, so no -a nor "Attack-modes" reference should be there.

@atom:: This line should be removed from --help of oclHashcat-lite:

Code:

-a,  --attack-mode=NUM             Attack-mode, see references below
