Invasion Mod

NOTE: This release incorrectly shows up as v1.1.5 in crash reports!

This is the first updated version of the Invasion Mod, bringing a lot of QoL improvements as well as bugfixes.

• Chat messages are now colored and translatable (also made many other improvements to them)
• Added Nexus damage sound and changed Nexus destruction sound
• Fixed a total of 11 missing sounds as well as their categories, allowing players to adjust the volumes (categories: "hostile" for wave begin and "master" for end sounds)
• Added German translation (if you're speaking any other language, I'd appreciate it if you created a PR containing any further translation!)
• Several QoL improvements to the /invasion commands
• Fixed Infused Sword heart particles not being visible to other players
• Items can now be shift-clicked into the Nexus
• Readded Waila support for the Nexus, now also showing Nexus wave and HP (the latter seems to not update correctly), compatible with the latest 1.7.10 version of Waila
• Reverted Material Probe crafting recipe change made in v1.1.5
• The Engineer's Hammer is now hidden in NEI
• Removed update checker
• Tiny performance improvements
• Slightly improved some log messages
• Added a Nexus logo in the mod list, certainly the most important change!

There are no gameplay breaking/altering changes in this update.
