Improve our resource files

Our resource files suffer from many issues, for example:

• They contain redundant null terminators.
• They lack a unified and consistent syntax.
• The formatting is.. bizarre.
• They contain useless sections that don't affect the runtime.
• They have some strange cases like "I'm not sure how to translate this, so let's just make this string empty".
• They are sometimes inconsistent between the translations and the default (en).
• They sometimes contain needless file separation between main and language related resources.
  ... And the list goes on.
