mod_admin_shell: Allow setting roles when creating user

net.server_epoll: Ensure calls to :write() return something With opportunistic writes enabled, writes can return what :onwritable() returns, thus :onwritable() should return something sensible at each spot. Should prevent whatever caused > Error writing to connection: (nil) Tho this was probably harmless

MUC: Allow modules a chance to act prior to room destruction

mod_cron: Expose the One Timer via module environment This makes it easier to reschedule or otherwise manipulate the timer from e.g. the shell, which is handy for debugging.

mod_http_file_share: Fix to take retention time into account It was lost in 6f4790b8deec when switching to mod_cron.

mod_http_file_share: Improve consistency of terminology in logging Prefer 'prune' over 'delete' since it more strongly implies removal of excess.

mod_http_file_share: Rename variable for clarity

mod_http_file_share: Fix deletion counter Before aa60f4353001 each loop had its own counter, seems incrementing of one of them was lost. But only one is needed anyhow.

mod_http_file_share: Back out 876e1b6d6ae4

mod_http_file_share: Recalculate total storage usage weekly instead of daily Before mod_cron this job ran less frequently than the upload removal job. Running them at the same frequency seems wasteful somehow, plus the total should not drift away from the true value that fast.
