Travis: notest install Catalyst + try multi-line

In order to reduce the total Travis build time, we're now installing
Catalyst and its dependencies w/o testing

Also, trying out a config with long lines split for better
readability... Not sure if it will work or not
(but http://lint.travis-ci.org/ says it will)
Travis: nope ... multi-lines don't work
Merge branch 'master' into travis-test
Travis: re-add jobs for 5.12, 5.10 and 5.8
Removed rouge RapidApp::CatalystX::SimpleCAS ref - #62
Officially require perl 5.10

There are currently some 5.10+ features in the code, such as //=
operators, that make it incompatable with v5.8. Officially requiring
5.10 now.

Later on it may be worthwhile to add support for 5.8...
