arv: AN3: make 3-edit limit a soft restriction

Per a request at WT:TW; useful for 1RR situations or slower-moving edit
wars.
Also grammar fixes.
morebits, protect: suppress warning when tagging a fully protected page

This confirmation popup was pointless - usually the admin had just
protected the page, and then they were asked whether they really wanted
to edit a fully protected page!
protect: fix bug relating to templateeditor protection

I knew I was a Wikipedia editor when I looked for the "This is a minor
edit" checkbox before committing this trivial bug fix...
welcome: rename {{welcome-anon-vandal}} to {{welcome-anon-unconstructive}}

Per request at WT:TW.
welcome: place {{welcome-screen}} with static=true

I probably shouldn't make this kind of unilateral change, but I really
do feel sorry for new users who get this amateurish, distracting,
annoying bouncy WP logo slapped on their user talk page - some welcome!
welcome: alter description of {{welcome-anon-constructive}}

Per request at WT:TW.
warn: Suppress linked user name in edit summary of {{uw-bite}}

Would require hacky post-processing to work correctly (like uw-socksuspect) but
isn't really necessary to start with, so let's go with less hacks.
