lib.FileContext.is_gettable: Add property

Browse source 
Analogous to the is_dir() method, add an is_gettable() method: The last
commit introduces FT_COMPOUND, a file type which is a hybrid between
directory and regular file. is_dir() succeeds on it, so is_gettable()
symmetrically provides a test find out if get() also works on a file.
