Issue #6 - Ability to pass several bug numbers to apply

git bz apply 1 2 3 4
will now apply the patches from bug reports 1, 2, 3 and 4

There is a check to prevent patches from the same bug reports to be
applied.

Say you have 3 depends on 1
if you apply 1 2 3 you will have:
 patches from 3
 patches from 1 (if you follow the apply on cascade)
 patches from 2
 # patches from 1 will be skipped if applied on cascade previously
