Mathias Gumz fff0abad76 Improve I18n support
Among the first steps to produce better i18n support is to test the created
translations adhoc without running "make install". To achieve this, fluxbox
now honors several environment variables:

- NLSPATH: fluxbox won't create the absolute path to the catalog and thus
  catopen() is free to use NLSPATH as described in the manpage. Example
  given: "/tmp/%N" will pick "/tmp/fluxbox.cat". %N refers to FLUXBOX_CATFILE.

- FLUXBOX_CATFILE: By setting FLUXBOX_CATFILE the users can make fluxbox to
  use a different name for the catalog file.  Default: "fluxbox.cat"

- FLUXBOX_CATDIR: Per default fluxbox tries to find FLUXBOX_CATFILE at several
  places. Setting this environment variable allows to point fluxbox to a
  different search path for the catalog files.

Then, fluxbox tries catopen() first without changing the deduced catalog file
name. After that it applies some heuristics to get a good catalog file name.
