Faerie dust

Previous versions of wig were based on a plugin system, but this has been changed, as the structure was somewhat complicated. The new structure should be more simple and it should be easier to get an understanding of the process. Another focus has been commenting the code - some parts still lack, but it has been improved.

The process of detecting CMS versions has also been changed - in the previous versions all fingerprints were checked before exiting. In this version 'wig' defaults to exiting as soon as the first CMS has been detected. This can be changed at run time though. With this change 'wig' makes less requests and exit faster.

This version of 'wig' also detects popular JavaScript libraries, and interesting files such as admin pages, readmes, etc.
