URL: http://hg.pidgin.im/soc/2012/sanket/statscollector-2.x.y/rev/30274be76c14

Description:

Add support for plugins

Now the plugins which are loaded unloaded can be recorded in the stats file.
This way we can detect various plugin usages as well. There are a host of TODO's
as of now.
* Handle case of corrupt XML files
* Some of the plugins reported are not required in the report, namely
"core-ssl", "prpl-*" etc. Though I have some hacks for prpl-* BUT we need
a better distinction for plugins to be recorded.
