Fixed a ban time saving bug when disconnecting

Bug caused by my latest experimental fix

2.0.7 - Forward update and data saving on unload

Those changes are experimental and could cause issues. More testing is advised.

2.0.6 - multiple improvements

- Improved sm_ctban_offline command by supporting a custom duration and reason
- Added quotes ("") support for sm_ctban_offline and sm_unctban_offline. Previously, quotes weren't removed properly.
- Improved code visibility in some places
- Fixed a bit the french translations

Fixed duplicate SQL connections being created on map change

2.0.4

Simple fixes:
- Removed a useless query that was causing a ban duration reset when a map change occured (discrepancy between ban time variable and data from the database due to a problem with the order of the queries)
- Fixed (re)loading the plugin mid game preventing banned players from having their ban time properly loaded, thus making the plugin think it was a permanent ban. Reconnecting fixed that, but now it shouldn't happen anymore (I hope).
