* I dislike the global infection RSpec does. This commit is a first step
to get a rid of it.
* Also remove the need for `require 'spec_helper` in each spec file with
adjusting `.rspec`.
Rationale:
* Console output lines are limited
* The more "valuable" information I see at once (without scrolling) the faster I'am
* I'm normally not in "tuning" mode.
* Can always add it when I need to tune. (But in this cases I'll profile
most likely)
* Mutator and Generator where merged.
* A single pass over all duplications was made.
* It is clear a specific handles?(node) code for finding mutators
is needed. Like virtus does for attributes, should also cache.
* Does not pass on 1.9 mode currently as blocks are unexpectly parsed
differend when it comes to a series of literal booleans.
* One of the main reasons behind mutant was to get a rid of rspec-1.3
in my toolchain.
* Remove most of mri specific stuff from Gemfile.
* Remove of mri specific taks will happen later, will heckle locally
with external rspec-1.3 + heckle setup.
* Mutant should be self hosting as fast as possible :P
