Changed Fragment links to Anchor links, however it's is slighty confusing what the right name for the thing is.
According to w3.org: "Some URIs refer to a location within a resource. This kind of URI ends with "#" followed by an anchor identifier (called the fragment identifier)." - http://www.w3.org/TR/html401/intro/intro.html#fragment-uri
After doing some research in the most common used name for the #some-link identifier I came to the conclusion that most of the time (about 70% on StackOverflow/BlogArticles/Interwebz) Anchor-link was the term used to describe the identifier. Imho, Anchor is the prefered term for the identifier.
Is it acceptable to change fragment to anchor, since it seems more used?
Move functionality from static start and destroy functions into instance
methods, allowing these to be overloaded. This works the same way as
calling Session::set() which then in turn calls inst_set()
Additionally use Injector to create the default Session instance to
allow the class to be swapped out.
Corrected many broken link-renderings. Also removed the "Related" link to [genericviews Module](http://silverstripe.org/generic-views-module) because it doesn't work, and I can't it elswhere.
There's no way to make things like [api:DataObject->beforeUpdateCMSFields()] work, is there?
I removed those kind of api tags (the links yielded a 404 page), and corrected a few other link-rendering issues.
Corrected a mistake: to make a new locale available (in particular for use with silverstripe/translatable), i18n:common_locales needs to be updated, not i18n:common_languages.
CustomMember was extending the wrong class to be able to reference $this->owner.
Also, changed CustomMember to MyMemberExtension to remain consistent with the initial example.
