Add an option to not enable WAL (should help in #399)

Include git repo in build so we get version

Removed list of mounted routes at startup by default, with option to add it back. This would get annoying when starting the server frequently, because it printed ~130 lines of mostly useless info

Added config option for icon download timeout

Updated Email Templates
