Upgraded dependencies and fixed tests for that relied on deprecated helpers.
Fixed deprecation warnings.
Fixed issues caused by upgrading friendly_id.
ActionView::RecordIdentifier was bleeding into other specs and causing failures.
Adopted strong paramters.
Removed trailing whitespace.
Fixed stub missing after retrival from database.
Fixed failing test by adding uniqueness validation back in.

I'm not sure why it was removed in https://github.com/refinery/refinerycms-portfolio/commit/a585646fd792e5c27f3a5769e5862d6622f67d3c#diff-1b689fdba31b680d215b27391b05f2e9L22. If there was a reason then the correct solution would probably be to remove the failing test instead.
Updated readme.
Removed unsupported rubies.
Replaced dynamic finder deprecated in Rails 4 and removed in 4.1.
Fixed bugs found in real world use.

Clearly there is no test coverage of these cases.
Replaced deprecated thumbnail call removed in Refinery 2.2 by taking advantage of the tools we already have.

This bug didn't show up until we could actually add images.
Used correct Rubinius code for RVM.
