API Docs: Clarify BLooper::PostMessage and BMessenger::SendMessage

... docs to make it clear which methods work synchronously and which work
asynchronously. A small number of related edits are included as well as a
couple of pedantic whitespace changes. Clarify sync vs. async reply
handling better in BMessenger class description. Add The to make sentences.

API Docs: various AppKit improvements

BLooper: API to hijack existing thread.

I need this to use loopers in WebKit, which spawns threads and expects
to be able to turn them into event loops later on.

This is the pattern already used in BApplication, we may as well make it
available elsewhere.

Update App Kit Documentation.

The biggest change is the addition of \since to each method. I've gone
through old versions of the BeBook and documented what version of BeOS
each method was introduced in. I'm only counting production releases
so I'm starting with BeOS R3 ignoring all DR and PR releases. Likewise,
all methods new to Haiku are listed as being introduced \since Haiku R1
ignoring alpha releases.

Assign class docs for app and support to libbe group, not libroot

Move app and support class docs from libbe to libroot.

Also a few more style and spelling fixes.

Big docs cleanup.

* Fixed headers including:
- All rights reserved not All Rights Reserved.
- name, email@domain.com not name <email@domain.com>
- tabs and spaces
- Authors: not Documented by:
* Renamed string.dox to String.dox
* Renamed midixxx.dox files to MidiXxx.dox
* Moved images into images subdirectories and updated Doxfile.
* Re-format all files with tabs instead of spaces.
* Fix many spelling mistakes.
* Added all files, classes, structs, and enums to libbe group.

Merge work by John Scipione on the Haiku Book.
* Some new classes documented
* Screenshots for the interface kit controls
* A lot of typo fixes
* Some css tweaks

This has some backporting to the current version of Doxygen, since
there are experiments to get coloring similar to the one in the Be
Book that will hopefully be upstreamed in Doxygen.

Handler.dox:
- Small link fix
- Clean up the titles of the subsections a bit: these are reused in the looper documentation and they sort of clashed before.

Also, new documentation for Looper.dox!
