Include ui, liveinst, and lang-table strings in po updates (#515411)

We were losing strings from liveinst/liveinst.desktop.in, ui/*.glade,
and lang-table whenever update-po would run.  Expand the po/ Makefiles
with Rules-lang-table, Rules-glade, and Rules-liveinst.  These files add
targets that generate the source files that the main po Makefile targets
will read.  Use intltool-extract to generate these source files from the
glade files and the liveinst files.  For lang-table, construct a source
file manually.

Modify scripts/getlangnames.py to open *.gmo files instead of *.mo
files.

In the ui/ and liveinst/ subdirs, add the *.h files to CLEANFILES so a
'make clean' operation will clear them out.
