* When the link target text is changed, only change the URL mode if the user
hasn't explicitely set the type (internal/external).
* Improve the conditions for the display of the 'external' and 'exists'
link-target messages.
* Validate the link target (i.e. show messages) not only when the text is
changed but also when the target type radio is changed.
* Rename the TitleInputWidget.isExternalLink() method to
looksLikeExternalLink(), to make its purpose clearer.

Refactor the code for selecting the first match, so it can also
be called from the look-like button method — this will be changed
once the whole link-inserter dialog is OOUI.

In order to get a better look-up experience (images, description,
redirects, and disambigutation pages listed last), swich from
a custom title-autocomplete input (that used jquery.suggestions)
to OOUI's standard one (which is used in a bunch of other places
in MediaWiki).
This means a fair bit of code can be deleted from
jquery.wikiEditor.dialogs.config.js, and some of it moved to
the new OOUI classes.
This patch aims to be the minimum required, and so leaves a few
things for subsequent patches (such as converting the other parts
of the insert-link dialog to OOUI).
