After implementing the BMimeType::GetInstalled[Super]Types()

Browse Source 
functionality, it became apparent that some restructuring was
needed if I wanted to keep things clean and managble.
storage/MimeDatabase.{h,cpp} have been broken into:

storage/mime/database_support.{h,cpp}
+ MIME database constants
+ high-level database access functions like open_type(),
  read_mime_attr(), etc.

storage/mime/database_access.{h,cpp}
+ atomic read functions
+ is_installed()
+ get_icon_data()

storage/mime/Database.{h,cpp}
+ Mime::Database class, which is responsible for all write,
  non-atomic read, and mime monitor functionality.

storage/mime/InstalledTypes.{h,cpp}
+ Helper class for Mime::Database::GetInstalled[Super]Types()

storage/mime/Supertype.{h,cpp}
+ Helper class for Mime::InstalledTypes

I haven't merged my intial, somewhat cludgy GetInstalled[Super]Types
implementation into the new setup yet. That comes next, and it ought
to be a more graceful implementation now.

I also implemented BMimeType::Get/SetSupportingTypes(), though
they haven't been tested yet (sorry).
