Adding docblocks and visibility keywords to methods
Reorder methods and variables to follow the SS coding conventions

The coding conventions is mentioned here http://doc.silverstripe.org/framework/en/trunk/misc/coding-conventions#class-member-ordering
Make SubsiteDomain#getCMSFields extendable
Adding docblocks to SubsiteDomain
Fixed translation namespacing

The TEMPLATE.ss.ENTITY wording stuffs up the YAML
parser in transifex, which made most translations
invisible to SilverStripe since they're indented wrongly.
Also removed empty FR file since Transifex complains about it on upload.

Merge pull request #121 from stojg/pr/cleanup

Minor cleanup of subsite code
Do not change the session-stored subsite, if session is not enabled.

This causes issues with Security::findAnAdmistrator which incorrectly
forces the current session-stored subsite to 0 - it uses
Subsite::currentSubsiteID before the session support is enabled, and
hence obtains wrong value.
