WL-907 Removed the 'Tabs Displayed' control from the Order Active Sites page.

Within an Oxford hierarchical portal, there is no corresponding meaning for a
'Tabs Displayed' control, so whilst this is non-functioning and harmless it
could otherwise prove distracting to the novice user.
WL-2754 Rename 'My Active Sites' to 'My Sites'

WL-533 Changed 'Customise Tabs' to 'Order Active Sites' in preferences.

WL-462 Further wording changes to what was the 'customize tabs' page.

In a vanilla Sakai set-up, the 'Customize Tabs' page within preferences,
enables you to specify the sites which will appear in up to (by default) 3
tabs across the top. In our set-up (or anyone using Oxford hierarchy) these
tabs are instead imposed by the system and reflect the ancestors to that
site within the hierarchy. Therefore, I've made some wording changes to
reflect this, in particular that the order only pertains to items in the
'Active Sites' tab.

Merge back, these are in /config now.
