Multiple issues with "Move Component to Separate file"

Some of these have already been mentioned, but this is my first time using it, so I'll summarize the issues I've found.

• New file doesn't get added to CMake if you add a subdirectory
• Dependencies (variables) don't get added
  • (Think of how required variables get turned into input parameters when refactoring a snippet into a method)
• Output parameters aren't being affected either. Property/alias needs to be exposed and references need to be updated 
• Unnecessary imports. Probably not high priority, but still not something that I think other refactor programs have.

Hope some of these are new!
