Modify project statuses to handle Verified & GIVbacks Eligible

[divine-comedian]

With this new feature the current "Verified" project status will be modified and a new status of GIVbacks eligible will be introduced.

Verified

Projects can become Verified by receiving the required amount of vouches through DeVouch - handled by #1740

Verified projects have less benefits than GIVbacks Eligible projects, they are:

• can be boosted by GIVpower
• is affected by instant boosting (shows higher up on list of projects when sorted by GIVpower)

GIVbacks Eligible

Projects can become GIVbacks Eligible by following the current Project Verification process.

• Project fills out "verification form"
• Admin either approves or rejects application
• on approval from admin project receives status of GIVbacks Eligible

---

What we'll need ASAP @MohammadPCh is the ability to change project's status to either of these new statuses at least from the admin panel and be able to apply the corresponding benefits as described above for Verified & GIVbacks Eligible.
