Due to the changed jenkins url i did a whole rework of this plugin.

*Added build Check -> check if build is outdated -> download if true

*Added propper Text/Messages

*Removed the hard update option *Auto Restart* didn't think it was that usefull.

*Removed the whole floodgate download/auto option. since floodgate doesn't get updated that often i took that one away.

*Fixed broken code an the auto update cycle*

*NameChanged to GeyserUpdater*
therefore you will need to delete the old gfasupdater.jar and its folder!
