www/rubygem-redmine_acts_as_taggable_on: Update to 1.1.0

This update changes to a different upstream fork where there is now
support for Redmine 3.x. This is maintained by the same author who
created the Redmine Knowledgebase plugin which requires this gem.

www/rubygem-redmine_acts_as_taggable_on: Update RUN_DEPENDS for rails4

This port is a dependency of redmine-knowledgebase. Redmine now depends
on rails4. Changing the dependency to the newer gem that uses rails4
enables this module to be buildable/installabale again.

Not going to MFH as 2016Q2 has the old redmine that uses rails3.

Convert USES=gem:autoplist to USES=gem since autoplist is default

create USES=gem and update rubygem- ports to use it

Note that for now ports still have to have USE_RUBY=yes to use USES=gem
