Adriaan de Groot 9331a25905 [libcalamares] Remove Typedefs.h
- This small header file contained a few unrelated typedefs.
   Move those typedefs to the classes they relate to. This
   **does** mean that some consumers need to #include something
   else instead.
 - Use type names more consistently.

Editorial: why are **pages** responsible for creating the jobs?
