Context Menu for Tabs

Useful for now, whilst the Tab Bar is in an incomplete state, but will also be useful in a finished version. Each Tab should have a Context Menu with a Close command, as well as eventually, options for renaming the Profile/Tab Title, and changing the TabWidth behaviour.

For now, the Tab Title Text can be so long, you need to scroll with the mouse wheel to get to the close button on some tabs, so having a right click option would help for now.
