As you probably saw via pclasses-cvs, this is now working. Some notable 
changes from the p1 code are:

- MimeType is now default constructable (will need for serialization).

- MimeType is now container-friendly, and can be used as a key.

- MimeTypeDb is no longer a singleton, but a shared instance is provided 
via the conventional instance() interface. i changed this for a couple 
reasons, but one of them is because there are some cool potential uses 
for local Mime DBs in other parts of the code (later on) and in client 
code.

- MimeTypeDb no longer reads the system-wide mime db at ctor type. 
Instead this is delegated to the instance() object - only that object 
loads mime.types by default.

- MimeTypeDb::instance() is now post-main() safe, and the db is 
repopulated if instance() is called after the shared object has been 
destroyed post-main().


- Added MimeTypeDb::FileExtensionsMap typedef, plus related functions. 
File extensions mappings are now done once per MimeType media-subtype 
combination, instead of once per instance of MimeType. This change made 
making MimeType container-friendly straightforward, and also eases 
client-side use of MimeType (IMO).
