- Unexport Core::Internal::MainWindow and remove its includes.
- Move RssFetcher from Core::Internal to Core.
- Unexport CopyTaskHandler.
- Move TextEditor's completion support and Refactor Overlay
  helper classes from TextEditor::Internal to TextEditor as they
  are exported.
- Move internal BaseTextBlockSelection into private header.
- Unexport TextEditorOverlay as they are not used.

Should have been done earlier. 2.1.80 was burned in the pre-2.1.0->2.0.1
days, and we'd like to have odd subminor for 'working' and even subminor
numbers for pure cherry-picking release branches anyway.

- Move RSSFetcher to CorePlugin
- Rename RSSFetcher to RssFetcher
- Make RssFetcher more generic, allow multiple sources to be fetched
- Introduce Featured Items on Getting Started page
- Introduce dummy entry for Mobile examples, needs implementation once they are ready

Introduce some more private classes for the coreplugin,
use header include convention

Rename 'QML standalone application' to 'QML application'
and the 'old-style' QML applications to
'QML Viewer based applications'.

For the QML renaming:

Also introduce a indirection, modes have now types, edit and debug have
the same type, and editors do have a prefered type of modes instead of a
prefered mode.

That fixes the bug that if the prefered qml editing mode was set to
design, then in switching between qml editors would
- in Edit Mode: stay in edit mode
- in Debug Mode: switch to debug mode

Fix README, some spelling errors, remove contractions,
exclamation marks, correct some plural forms, join split messages.
Add QCoreApplication::translate to non-Q_OBJECT-classes.
Fix some lupdate warnings about discarding meta-data (//:).

It's more complicated then expected, to be detangled another day

Switch to Edit Mode once we constructed it in Core::init(). Switch to a

Using more *::Constants::ICON_* where it makes sense and
wrapping the file names into QLatin1String where they were
missing.

The increased usage of the ICON constants needed a few more
cross plugin includes of *constants.h, here and there.
I think that it is OK, since the dependencies were alredy there
icon resource wise.

A mostly mechanical change.

I now cache the scaled welcomemode background so it feels more
responsive when toggeling back and forth between modes.

The scaled pixmap has been reduced in size to speed up the
plugin loading and refresh times. Stylesheet has been
slightly optimized as well.

The text color was incorrect for certain dark color schemes,
including the latest Ubuntu theme.

This should keep QNAM from blocking the startup in some network setups.
