A few more quick fixes to the current build

- Added filtering options on server list
- Added pad lock icons for password protected servers on server list
- Fix for not being able to die while carrying gem
- Ammo counter less confusing for some weapons/items
- Fixed sentry gun build text always visible after late join

--------

Note: Most of the development team is now taking a few weeks of summer-vacation, so this will be the last Hot Fix for now.

Have a nice summer :-)
