Deskbar: Resizable tray

* Adds max width and height arguments to
instantiate_deskbar_(item|entry).
* Old applications just stay with a 16x16 scaled icon, though.
* All used apps within the repository are converted to the new call
besides the input_server input method icon (that will need further
API changes in the input_server).

BDeskbar & Deskbar: export window bool settings to BDeskbar

Add methods to get and set "Always on top", "Auto raise", and "auto hide"
which are all booleans which control aspects of the Deskbar window to
BDeskbar.

Set the bool to the default value initially. Check if sending the
message succeeds, if so check the reply which also fills out the bool.
Don't check to see if reply succeeded because the bool will only be
overwritten if it did.

Follow the BDeskbar convention Is...() for getter, Set...() for setter
e.g IsAlwaysOnTop() is the getter, SetAlwaysOnTop() is the setter.

Define new message constants to call the newly created methods.
Follow BDeskbar convention: 'gtla' is used for getter, 'stla' for setter.
g/s for getter/setter, tla is an all-lowercase code unique to each
getter/setter pair.

Copy/paste these message constants into BarApp.h unchanged. Replace four
letter codes with imported message constants in BarApp.cpp and
BarWindow.cpp. Much nicer than using bare codes.

The new BDeskbar methods are all handled by TBarApp. The getters send
back a reply message containing the bool while the setters fall through
to existing setter cases.

BDeskbar: Style fixes

Update Copyright in cpp, add myself, alphabetize, standardize
Pointer style in cpp
Update some comments
Some 80 char stuff
pragma section headers
whitespace

Optimized includes. For example, BeBuild.h is almost always already included
via SupportDefs.h.

Finished unifying the Interface Kit headers:
* Fixed copyrights (puncuation and capitalization, removed authors from
headers)
* Updated indentation style
* Unified pointer/reference style
* Re-ordered some methods for better grouping where it could be done
(abd adopted source accordingly)
* Small coding style fixes here and there

No functional change intended.
