Look at locale aliases if initial search in compose.dir fails

The file "locale.alias" (located in the same directory as "compose.dir"),
contains following text:

"This file contains alias name of locale.
Each alias name is described within one line.
The first word is the alias name (simplified locale name)
the second word is full locale name."

Therefore, if initial search in the compose.dir fails to find a match we
make sure that a 'full locale name' was used in the initial search, if not,
we try again.
