Backgrounds: Rename CustomRefFilter to ImageFilter

... and simplify Filter() logic. Check that GuessMimeType()
status is B_OK. Rename imageFiltering variable to filtering.

No functional change intended unless GuessMimeType() errors.

Backgrounds: style fixes only

* Update copyright headers
* Fill in pragmas
* Eliminate superfluous B_USE_DEFAULT_SPACING, 80 char limit too
* rename msg variable to message

Partial clean-up.

* Made our struct stat POSIX compliant again -- the time_t fields have been
replaced by timespec fields. Via macros the structure is still source
compatible with the old one.
* Introduced header <compat/sys/stat.h> that defines the old stat structure
(as stat_beos) and conversion functions
* Introduced versions for [l,f]stat().
* Added symbol versions for BDirectory::GetStatFor() for sake of binary
compatibility.
* BStatable::GetStat(): Renamed the old method, changed its parameter to
stat_beos*, and and made it private. Added a new version (using up a
reserved vtable slot). It remains source and binary compatible.
* BRefFilter::Filter(): Changed the struct stat* parameter to struct stat_beos*
for sake of binary compatibility. This breaks source compatibility, though,
which we can't help, since the class doesn't have reserved vtable slots.
* Fixed several issues with the stat structure change, mostly adjusted uses of
BRefFilter.

BFilePanel::Show() is now virtual, so my previous change didn't work -
ImageFilePanel::Show() must be called explicetely.

* Renamed BGView to BackgroundsView, etc.
* Moved ImageFilePanel code to its own file, so that it can be reused easily.
* Moved BGWindow stuff into Backgrounds.cpp.
* Cleanup to match our style guide better.
