Install script aliasing

[Boston Vanseghi]

Is your feature request related to a problem? Please describe.
If a user wants to install gcc on Windows, they currently have to run ccake install mingw. There are a couple problems with this. MinGW will not be necessary on linux machines, as gcc should be the native toolchain. A linux user should therefore not be expected to run ccake install mingw, but ccake install gcc instead. Ideally, both windows and linux users should have to type the same thing, which should be ccake install gcc.

Describe the solution you'd like
If a Windows user types ccake install gcc, CCake should really treat the identifier gcc as mingw, but only on Windows.

Describe alternatives you've considered
