Add defaultseason attribute to TV Show regex

Allow the default season to be set for TV shows. This will be used when
no season is found in the filename. If no default is set, use 1 as the
default season for the sake of both backwards compatability and to
conform with the assumption that season 1 is the standard season, as
opposed to season 0 (usually used for special episodes).

Use of this feature is through the advancedsettings.xml configuration
file, under the tvshowmatching tag. An example is as follows.

<tvshowmatching action="append">
   <regexp defaultseason="0">[\._ \-]()S([0-9]{1,3})([^\\/]*)-</regexp>
   <regexp defaultseason="1">[\._ \-]()E([0-9]{1,3})([^\\/]*)-</regexp>
   <regexp>[\._ \-]()X([0-9]{1,3})([^\\/]*)-</regexp>
</tvshowmatching>

Here are some sample filenames run through these settings.

Filename                XBMC Result  Comment
'Foo - S001 - X.avi' => 'Foo - 0x1'  (Season forced to 0)
'Foo - E001 - X.avi' => 'Foo - 1x1'  (Season forced to 1; not needed)
'Foo - X001 - X.avi' => 'Foo - 1x1'  (Season defaulted to 1)
use < 0 rather than == -1 as it's a little clearer once operator==() is implemented correctly
fix AddonVersion::operator==() so that it is consistent with AddonVersion::operator<()
fix up AddonVersion::Test() now that == behaves as it should, and add some basic info as to what is expected in a doxy comment
