Add mw vars files and ext + skins tasks

This change leaves a few TODOs in the vars
file for things that are still missing.
These miight need to be split into correct repos.

Also on the TODO is making the extensions track
branches where appropriate.?

This is still an idea and a work in progress!

Before this is tested we also need to create a
branch of the current version of MW that doesnt
have any skins or extensions in it or submodules
pointing to them!
Add final extensions (moved to orain repos)
Add missing skins from Gerrit
Use mediawiki-core REL1_23_noext branch
Fix use of items in skin and ext git stuff
Remove GoogleSiteVerification

This is not used and is causing an issue
when being pulled
Use Orain fork repo for NativeSvgHandler
Add slow tags to mw ext and skin updates
Make all ans-* quick scripts more advanced

This allows passing of --skip-tags and --branch
Match recent changes in mediawiki-core

BlueSky skin
AdSense Extensions
Update VectorBeta version
Remove skins that are still in mw1.23.3
Fix VectorBeta extensions version > REL1_23
Have 2 different cron jobs to run ansible
Fix ans-run quickScript for tags
Merge pull request #364 from Orain/addIndiExtPulling
