Hi everyone!

In this update I'm introducing faction banners. Owners (highest-ranking members of a faction) of factions can now add custom faction banners to their faction using the /changefactionbanner command. Other players can obtain this banner by using the /buyfactionbanner command. The price of the banner can be adjusted in the config file.

This update also contains a few minor bugfixes. Hope you enjoy it!

features:
- added an update checker (WIP)
- added banner system: factions now have banners
- added /buyfactionbanner command
- added /changefactionbanner command
bugfixes:
- fixed formatting issue with /changefactionname command
- fixed formatting issue with /listwarps command
