Modify class prefixing in Logger
Modify class prefixing in Logger

Previously Logger simply took the actual class name (minus any
namespacing) and used this in the log; however, some classes, such as
Plugin-namespace utility classes (e.g. Plugins\IRC\Connection) this is
undesirable. Now Logger removes any of the following prefixes from
the full name of the class, including namespace, and uses this in the
log:

- Icarus\Lib\
- Icarus\Plugins\
- Icarus\
