Add optional (fallback) grepformat to g:ackformat

[ku1ik]

grepformat can hold multiple values separated by commas. When parsing results Vim tries to match lines against each of formats specified.

I added additional format %f:%l:%m that doesn't include column. This allows using git-grep (that don't have an option to output column number) with this plugin just by setting g:ackprg like this:

let g:ackprg = 'git grep -H --line-number --no-color'

Any chance for merging this?
