Updating `grm` alias to support rm of resources where path contains spaces

`awk '{print $3}'` will give us the path following `deleted:` in the git status
output, but not the full path if it contains spaces.
`awk '{$1=$2=""; print $0}'` effectively removes `#` and `deleted:` from the
grepped line, allowing us to retrieve the remainder with `$0`. Following this
we filter out spaces at the beginning of the line and escape all remaining
spaces with `awk` and `sed`.

I suppose this could be done more elegantly (maybe
`awk '{print substr($0, 0, N)}'` where `N` is equal to the number of characters
preceding our desired path), but I honestly can't be certain of git's behavior
to expect it to work the same all the time (i.e. is it always 14 characters?
what about tabs?). Probably a noob issue...
