When repository contains a Slack type hook,
it changes original payload content.

This patch fixes it by using a local object to store
newly created Slack payload instead of assigning
back to the same variable.

Used by Android >= 5.0 to make the top bar colored.

- Update locales

path.Dir can't handle Windows case, must use filepath.Dir

This is fixup for ea375c0dcc. The bug was not
visible because commit.RefUrl was always returning empty url due regression
