Clockin changelogs:

Changelogs don't include small changes I make to fix small problems, they only contain major changes or additions/removals.

Potentially fixed the /clockedin dm command sending the same embed over and over again.
Potentially fixed the /alldata dm command sending the same embed over and over again.
More permission checks since I'm tired of telling everyone to give the bot the EMBED_LINKS and SEND_MESSAGES permissions.
/force-clockout user now shows the total amount of time added.
/settings contains new subcommands:
- /settings giverole toggles the giving and taking of roles on or off.
- /settings onerole has you set one role to give to someone when they clock in or out (the same role for all masks).
- /settings maskrole has you set a role to give to someone when they clock in or out (one role per mask).
- /settings currensettings has been updated to reflect these new settings.
- By default giving and taking roles is turned off.
- Giverole requires the MANAGE_ROLES permission. If the bot hasn't been granted this permission it will tell you so and not give or take any roles.

Minor changes to /clockin to make defaults work.
Minor bugfixes (for my sanity).
/settings contains new subcommands:
- /settings setdefault lets you set a default by attaching a role to a mask.
- /settings forcedefault lets you toggle the defaults system.

Export command fixes
- Sorting now works correctly
- Nicknames now work correctly
Memory optimizations (less automated restarts)
