Changes submitted by Peter Funk (some fixes/additions by B.Warsaw) to 

make pygettext more compatible with GNU xgettext, specifically:

Added -E/--escape for allowing pass-thru of iso8859-1 characters above
7 bits.

Added -o/--output option for renaming the output file from
messages.pot (there's overlap with -d/--default-domain, but GNU
xgettext has them both).

Added -p/--output-dir for specifying the output directory for
messages.pot.

Added -V/--version for printing the version number.

Added -w/--width for specifying the output page width (this is because
now pygettext, like GNU xgettext will put several locations on the
same line to cut down on vertical space).

Added -x/--exclude-file for specifying a list of strings that are not
to be extracted from the input files.

Bumped version number to 1.0

Try to import fintl and use fintl.gettext as _ if available.  Fall
back is to use identity definition of _().

Moved the escape creation to a function make_escapes() so that its
behavior can be controlled by the -E option.

__openseen(): Support the -x option.

write(): Support -w option and vertical space preserving feature.

main(): Support new options.
