sqitch_tool

[brokenpylons]

Hi,

I made a refactoring utility sqitch_tool, which allows renaming (moving) and removing changes and the associated files in the deploy, verify and revert directories. It basically solves #290 and #295.

I mostly made it to scratch my own itch, so it's written in OCaml (it would probably take me more time to learn Perl, than it took me to write this). The implementation uses a character-level recursive descent parser for parsing sqitch.plan, which might be of interest.

Woah, how fun is that? :-)
