- Restored removed built-in snippets.
- Revert a built-in snippet.
- Reset the snippets collection.

Reloading and synchronizing are now directly accessible from
the collection interface.

And mark the completion item as a snippet.

When editing one variable from a code snippet, all other variables
with the same name are updated accordingly.

Provide an interface so users can create/edit/remove snippets.

Make lookup for a delimiter a bit faster.

Cache matches of the RegExprRule to avoid unnecessary calls.
This is essentially the same optimization existent in Kate.

A colateral effect of this implementation is a mechanism to
notify the rules when a progress (highlight of the current
line) is finished.

Also add the alternative way: IOptionsPageProvider, which states
a category, and is asked for a list of options pages for that
category when it is shown.

This is basically a continuation of the commits which
refactor code out of the base text editor. For instance,
36fa1de4 and
3a684586.

Also removed the doXXXX() forwarding methods.

Use the editor's displayName for the window title.
Also there were missing change signal emissions in setDisplayName
implementations.
Moves the actual handling of the window title from Session to
EditorManager (so it now is also done for the hypothetical case of no
project explorer plugin).

QFontMetricsF::averageCharWidth seems to always return a fractional size
(at least on Linux/GNOME with DejaVu Mono), even when the font is not
actually drawn at sub-pixels. This caused the visible wrap column to
appear in the wrong place.

As a workaround, use the width of the character 'x', which is pretty
average and does align to pixels when needed.

E.g. on Mac.

Block highlights should still be visible even outside the margin (when
margins are displayed naturally), since it acts only as indicator of
the character limit.

Apparently this had already been noticed before and recently there was
a merge request (no. 204) with an attempt to fix it. However, the
implementation was not handling it in a nice form. This is a small
patch that solves the issue and keeps the editor beautiful. (Check
the merge request for more details.)

Consider some refactoring with the related options as well to avoid
overriding user's settings.

This leaves the code prepared if we decide to ship some of the Kate XMLs (still
a pending decision). In this case the installer needs to be "notified" and the
Kate files put in the repo.

An addition check for actual XML files in the searched directories is also added.
