Bug 17082: Translatability: Fix sentence splitting in member.tt

This patch fixes sentences splitting in file
koha-tmpl/intranet-tmpl/prog/en/modules/members/member.tt

Fix is done with a new .inc file because the code is the same as in
koha-tmpl/intranet-tmpl/prog/en/modules/members/memberentrygen.tt

To test:
- Carefully review code changes
- Test on a fresh install without example data (or save database
  and test with empty tables 'branches' and 'categories')
- Go to Home > Patrons (members-home.pl)
- Verify that a warnings appears aubout missing libraries and patron
  categories
- Try to add a new patron (memberentry.pl)
- Verify that the same messages are triggered
- Verify that messages disappear as appropriate as soon as a library and
  a patron category are defined.
