Update modules/twinklewarn.js

Removed a deleted warning template.
warn: add red notice to show correct use of {{uw-username}}

Per discussion at WT:TW and WT:UAA.
secure is now redirecting 301 back to normal
welcome: add pref to disable signature on custom templates

Per issue #140.
warn: correct placement of red notice div in DOM
talkback: add Teahouse talkback template
morebits.css: small tweak to QuickForm header selector

This is needed for upcoming changes I plan to make. It works in IE9 and
latest Firefox, and as such it probably (!) works in Chrome.
Readd {{overcoverage}} to category list

Seems {{overcoverage}} has been missing from category list all this
time!
morebits: allow multiple elements in a subgroup

* Subgroup styling moved out to morebits.css
* Make subgroup IDs unique (except for 'option' elements; need to fix
this)
* Removing the attribute name="id" on every QuickForm
tag: add enhanced support for {{merge*}} tags

* Rationales can be posted on the article talk page.
* Multiple articles can be tagged at once with the appropriate merge
tag.
morebits: unify status object construction logic

Also, any errors are now logged to the browser's JavaScript console.
This is helpful if using morebits in a situation where the status system
is not/cannot be used.
xfd: add {{tfm}} nomination functionality

You can now choose to nominate templates for merging via the TFD dialog.
It tags both templates involved but doesn't notify both page creators
yet.
warn: show red usage message on {{uw-coi-username}}

This is in addition to that shown on {{uw-username}}.
Per request at WT:TW.
protect: move unprotection to top of preset list for admins

Just so it's always accessible.
change #bodyContent to #mw-content-text to improve skin compatibility

Per note at WT:TW.
fluff: don't identify edits as vandalism in the rollback edit summary

Per discussion at WT:TW. It's generally poor form to label edits as
vandalism in such a public and uneditable place as an edit summary.
protect: notify admins of existing PC protection when about to protect a page

This can't work until the fix to bug 24068 is deployed. Right now it
hasn't even been merged yet, so we could be waiting for a while.
