BMessage::SetString() was broken.

* We cannot use the macro for this, unfortunately.
DriveSetup: solved a few issues of CreateParametersPanel.

* I obviously wasn't really done last time: now the panel behaves as it should.
Cleanup.

* Removed superfluous redundant comments.
Cleanup.

* There is no BDiskSystemAddOn::GetInitializationParameterEditor() method,
  and it's therefore never being called.
DriveSetup: Added support for changing partition parameters.

* Does not seem to work yet, though. The intel disk system should support it
  now, but apparently the partition's delegate is not yet fully initialized
  for whatever reason.
%T placeholder (localized Terminal name) for title mask

* %T placeholder added into the set, available for customizing main
  Terminal window title. It should be typically replaced by the
  application name localized for the currect system locale.
* Use B_TRANSLATE instead of B_TRANSLATE_SYSTEM_NAME for the first
  menu entry in the main TermWindow menu. The meaning of "Terminal"
  term in this menu is the "Terminal session" but not the "Terminal
  Application" so using separate catkeys entry for this menu item
  avoids this inconsistency in Terminal UI localization;
* Fixes #7586
Use B_TRANSLATE_COMMENT for "Terminal[sessions]" sub-menu

* Explain the meaning of the "Terminal" menubar entry using
  B_TRANSLATE_COMMENT with extra info for translators;
* Suggested by Oliver. Thank you!
Store and read show/hide clock setting on disk.

So that the setting will persist across reboots. This is a Deskbar
setting, not a "clock" setting. Theoretically someday if we make
it so you can replace the clock with a different clock widget we
still want to store whether or not to show the clock widget as a
Deskbar setting.
Fixes #9456
intel disk_system: Renamed file to match class name.

* Renamed CreationParameterEditor.(cpp|h) to PrimaryParameterEditor.(cpp|h)
  as that's what the sole class in there is called.
Removed the help menu from Magnify (#5012)

No other Haiku app has a help menu, we have the user
guide for that. One time we may want to link the
appropriate user guide page into all apps...
Update BAboutWindow to use B_CLOSE_ON_ESCAPE flag.
Fix warning and cleanup for BPath docs
Move BQuery docs into Haiku Book.

... removing the docs from the .cpp and .h files and cleaning up as usual.
Update translations from Pootle
Make FirstBootPrompt write the settings immediately upon launch.

If a user does not select anything, the default settings will be written.
Part of #9427
Changed the logic for launching FirstBootPrompt.

Always launch on read only medium.
Launch when the Locale settings file does not exist.

Fixes #9427.
Renamed file. No functional change.
s/OpenBeOS/Haiku
Automatic whitespace cleanup. No functional change.
Rewrote copyright header.  s/OpenBeOS/Haiku.

Slight cleanup to included headers.
