Whereas previous efforts were focused on the user-facing side, this commit replaces Citra references which are present in the codebase itself. This should be the last time a change like this is ever necessary.
- Rebranded executable files to reference Lime instead of Citra
- Rebranded many files in the source tree to reference Lime instead of Citra
- Rebranded many resource files to reference Lime instead of Citra
- Rebranded all instances of Citra's reverse DNS to Lime's reverse DNS
- Other small misc rebrands
