mail: switch 'Set to' window to use layout lib

'File -> Close and -> Set to' used a hard-coded window size and
control/button layout. Switch this to use the layout library for proper
scaling.

* Now stores signatures and status files to "~/config/settings/Mail/" instead
of "bemail".
* Automatic whitespace cleanup.

first part of a big cleanup of the Mail code
* separated window, app and context menu code
* got rid of all the global variables (which were accessed completely without
locking, and the code with regards to the preference window sill needs
fixing)
* extracted some defines and helper functions to MailSupport.cpp, though I later
saw Utilities.cpp...
* got rid of the FONT_SIZE define which was used in some (but not all) controls
to override the system font size
* worked in Header.cpp to get the controls layout font sensitive with correct
alignment too, some problems remain when resizing the window

* Renamed BeMail to Mail.
* The settings are still saved in "config/settings/BeMail Settings", though.
