Bug 12061 - tmpl_process3.pl - Multiple source dir

This patch adds the option to use multiple source
dirs for tmpl_process3.pl on create/update actions.

To test after patch:
A) Old
1. install
cd misc/translator
perl tmpl_process3.pl create -i ../../koha-tmpl/opac-tmpl/bootstrap/en -s bootstrap.po -r

2. update
perl tmpl_process3.pl update -i ../../koha-tmpl/opac-tmpl/bootstrap -s bootstrap.po -r

3. install
mkdir test
perl tmpl_process3.pl install -i ../../koha-tmpl/opac-tmpl/bootstrap -s bootstrap.po -r -o ./test -q
- check same number of files
ls -lR ../../koha-tmpl/opac-tmpl/bootstrap | wc -l
ls -lR ./test | wc -l

rm -f bootstrap.po

B) New
4. create from multiple sources
perl tmpl_process3.pl create -i ../../koha-tmpl/opac-tmpl/prog/en -i ../../koha-tmpl/opac-tmpl/bootstrap/en -i ../../koha-tmpl/opac-tmpl/ccsr/en -s opac.po -r

5. update from multiple source
perl tmpl_process3.pl update -i ../../koha-tmpl/opac-tmpl/prog/en -i ../../koha-tmpl/opac-tmpl/bootstrap/en -i ../../koha-tmpl/opac-tmpl/ccsr/en -s opac.po -r

6. install (must give an error)
perl tmpl_process3.pl install -i ../../koha-tmpl/opac-tmpl/prog/en -i ../../koha-tmpl/opac-tmpl/bootstrap -s opac.po -r -o ./test

7. updated help
perl tmpl_process3.pl --help

Any other functionality must not be affected
