plugin support for F-Spot

[Stephane Delcroix <stephane delcroix org>]

Hi list,

I've spend some time lately to develop a plugin facility for F-Spot. So
far, I've a virtual plugin class, some methods to load plugins, and a
testplugin. Thanks to Thomas and his solution to bug #344534, I've also
a way to compile plugins without the F-Spot sources.

The main goal of this plugin facility is to provide (in a first time) as
many Export schemes as you can imagine. Export function like 'export to
my local photo store' will never ends up in the core of F-Spot (my
guess), but some people need this.

I'll be happy to see any comments, remarks, requirements...

regards,

Stephane
