Add pre-commit hook support
Bitbucket should support a configurable pre-commit hook. In fact, bitbucket should support all client side hooks.
NOTE: I am not referring to a pre-receive or a post-receive server-side hook.
The rational provided by Atlasian for not allowing hooks is that it would allow people to run arbitrary code on their servers. However, I do not see a reason to prevent any client side hooks from being configured.
