[Event] method renaming.

Renamed `Event#flag_for_sourcing` to `Event#flag_as_modified_for_sourcing`.

Also clarified the comment on the params argument that it can have a valued for the key `:processor`.
[git] cleanup .gitignore to be more precise.
[Setting] clearer variable names.
[gem] update to support gems.

Adjusted some of the gem specifications to allow more recent versions.

Dropped Capistrano from gemfile since I wasn’t actually using it.

Fix to factory_girl integration with cucumber (no longer need to include `factory_girl/step_definitions` from the gem).

Testing and preflight configuration.

rspec:
* Leave profiling to preflight (don’t use it during continuous testing / auto-testing).
* Turn on test order randomization by default.
* More configuration in `spec/spec_helper.rb`.
* Allow the new `expect` syntax (in addition to the classic `should` syntax).

autotest:
* Ignore the reports directory.
* Fix indenting.

simple_cov:
* Move coverage reporting from `coverage/` to `reports/coverage/`.

preflight:
* Cleanup comments.
* Fix indenting.
* Use descriptive option flags where available (e.g., `--quiet` instead of just `-q`).
* Add profiling flag to rspec.
* Update flog options for current version.
* Hide listing of files that have no warnings from the reek report (using the `--quiet` flag).
* Consolidate duplicated code when reporting the git status at the end.
[gem] update to Rails 3.2.11.

No code changes required — just update the Gemfile and run `bundle install`.
