Change reform to version 1.2.6

[rogerleite]

Hi @apotonick!

I cloned the project to see trailblazer working and test rails 4.2.0 version.

On Gemfile (https://github.com/apotonick/gemgem-trbrb/blob/master/Gemfile#L35) the reform gem was on "path". I changed to 1.2.4 and did the default setup and is working and tests are ok too.

Talking about this subject, i'd like to question some things:

• Do you know if trailblazer runs on rails 4.2.0? (Yes, see #3)
• This instructions on https://github.com/apotonick/gemgem-trbrb/wiki/Things-You-Should-Know to use trailblazer is still required on any new project?

Thanks and great work with trailblazer!
