[aur-general] Rename `identicurse` and `identicurse-nogit`

[Psychedelic Squid]

Hey, just wondering what the best approach would be for renaming
`identicurse` and `identicurse-nogit` to the more consistent (with other
AUR packages) `identicurse-git` and`identicurse`, respectively. In particular,
is there any way to prevent the current git users ending up on the new
non-git package, given the old git package and the new non-git package would
have the same name?
