This helps avoid conflict when detecting framework to work with.

With the previus commit, the ansible parameters are used in string
variable which cause the script to stop executing. Use eval force to the
string to run the command.

This helps making line length shorter and prepare for integration of
more optional tags to pass to ansible.

[IMP] Add flow command resource:publish

Hi Visay,

I think ./flow cache:warmup is enough to publish new resources but it is weird that we need to run one more command ./flow resource:publish.

However, I would suggest you to tag the current master brand to 1.2.* for Neos 1.2.* and merge my commit for Neos 2.*.* since resource:publish is not support for Neos < 2.0.*

Thanks,
Man
