Phrase reloading in xpages only checks system.xml for changes

[jesusbagpuss]

For xpages in ~/archives/ARCHIVEID/cfg/lang/en/static/, only changes to phrases in system.xml are reflected real-time.
An edit to the xpage itself will reload all the phrase files next time the page is requested, but changing a phrase contained within e.g. ~/archives/ARCHIVEID/cfg/lang/en/phrases/test.xml that is referenced in ~/archives/ARCHIVEID/cfg/lang/en/static/test.xpage does not get reloaded.

Notes:
~/perl_lib/EPrints/Update/Static.pm
sub update_static_file checks mod time of xpage file ($source_mtime) and resulting html ($target_mtime):
return if( defined $target_mtime && $target_mtime > $source_mtime );

It does not consider phrase files updates.

Notes2:
Major reworking in master branch using MapToStorage.
