cf 7.x-2.0-unstable1

There are two objectives with this early release:
1) Make a release to check and confirm that an incident like the one that happened to the release of 7.x-1.5, see issue #1562070, does not happen again.
2) Make an official, albeit unstable, release for testing and confirming the upgrade transition process from 7.x-1.x to 7.x-2.x.

For those who want to test the transition process, you must do the following:
- Be prepared to have to upgrade modules that depend on cf to their development versions in case they had to have some sort of compatibility adjustment. It is not known if this is required or not, thus the "unstable" status.
- Make sure to be using the 1.x series version of at least cf-7.x-1.6.
- Enable the following transition modules:
- CF 1.x Compatibility
- CF Database Options
- CF Settings
- After enabling said modules, replace the cf-7.x-1.6 with this unstable release (cf-7.x-2.0-unstable1).
- Run the drupal update.php script.
- FYI: during my tests, I ran into 1 issue where some of the updates failed to apply. It turns out that some sort of order of operations bug happens and some of the modules may update in the wrong order. I simply ran update.php a second time and the remaining updates managed to apply fine.
