Proposed draft for the thumbnail D-Bus specification

[Philip Van Hoof]

Hi Tommi, Rob and Havoc!

The three of you had comments about the Manager interface. This is now
removed and replaced.

A first draft[1] of a better proposal for registration of specialized
thumbnailers have been written.

I have not yet adapted the prototype[2] to use this, but this will
happen either today or next week.

Pleas let me know what you think about it.

Note about the protoype: now you can run a GModule made for the
prototype as a standalone specialized thumbnailer. This means that the
specialized thumbnailer specification can be tested with the prototype
this way.

This is the code that does this:
