Previously the whole line turned into a link. I think it looks a bit
nicer now.

Link position had the wrong offset. Also took out a redundant check on
token kind.

It popped up an error saying the file couldn't be found. Better not show
a link at all.

The BaseTextEditor was unconditionally setting the mouse cursor on each
mouse move event, after which the CPPEditor would set it as well when
the mouse was above a link. This caused some mouse cursor flickering, so
now the cursor is only set when it's supposed to change.

Also fixed an issue where the link wasn't removed when leaving the text
editor with the mouse while Ctrl was pressed.

By avoiding searching for the definition when it isn't necessary.

Cause blue doesn't fit nicely in all color schemes.

There's no place to jump to in these cases.

Allowed customizing the link for includes and macro uses and fix it for
highlighting the name.

Allows navigating the code using the mouse when pressing Ctrl. Suggested
a few times and also seen in other IDEs.

* Convert dots in filenames to underscores in header guards
* Don't indent closing namespaces in source file
* Consistent empty line placement

Fixes issues with handling additional dots in the filename in many
places.

Fixes: Introduce a cpp settingspage containing file naming conventions (lower case and suffixes). Reorder VCS settings pages.

RevBy: Optics/Naming checked by con
Details: Give IOptionPage an id() to differentiate from trName(). Make showOptionsDialog return a bool (applied) and give it an optional parent. Change Cpp and form class wizards, give them a Configure... button to change those settings.

This stuff was all over the place, a relic from before the editor
settings were unified. Now the initialization is only done in
TextEditorSettings.

Fixes the .pro file editor and the generic project files editor, which
before only used the font settings.

I couldn't find it since it was both hidden in the cppplugin.cpp file as
well as having an unnecessarily long name.

Didn't add anything to the TextEditorActionHandler.

Introduce setCodeFoldingSupported to the BaseTextEditor, and only
enabled it for the C++ and QtScript editors. This removes the useless
margin meant for code folding markers from the plain text editor and
.pro file editor.

Use _HPP for example for .hpp files, for example. Based on simply
putting the chosen extension in uppercase.

This code is already in TextEditor::BaseTextEditor::openEditorAt.

Small bugfix for column to jump to.

Don't look at the whole project. We're only interested in the symbols that we can resolve in the current file.
