Add version control URI schemes to registerProtocolHandler safelist

Add version control URI schemes to registerProtocolHandler safelist

This allows sites to register protocol handlers for version control
repositories.

I've confirmed uses of every one of these schemes in the wild.

BUG=651311

No L-G-T-M from a valid reviewer yet. 
CQ run can only be started by full committers or once the patch has
received an L-G-T-M from a full committer.
Even if an L-G-T-M may have been provided, it was from a non-committer,
_not_ a full super star committer.
See http://www.chromium.org/getting-involved/become-a-committer
Note that this has nothing to do with OWNERS files.
