appmanager action files: create and populate them

The appmanager action files (/usr/dt/appconfig/appmanager/*) are now
created properly for the main 4 languages supported.  As usual, the
en_US.UTF-8 locale is a symlink to C.

These files were previously created via the UDB database files via
imake.  Obviously we aren't going to be using those in autotools.

So, each language now has an appmanager/ dir in
programs/localized/$LANG/ that will create them properly on a make and
make install.  It uses a new appmgr.am template in localized/templates
to do this.

This also means all of these languages now can use the new actions
added by Antonis, even though they are not translated, they are at
least usable in those languages now.
