Makes Eris both compile and run properly on 515 version of BYOND.
Why It's Good For The Game
Don't have to answer "why my UI is white box" questions anymore.
Also people who play on different codebases won't have to reinstall BYOND each time they want to play on Eris.
Testing
Compiled and ran the code with latest version of BYOND, checked that debugger and TGUI work as intended.
