Add a "gifting server subscription" option so any member can support a server without admin perms

[Gabe || Игорь#6666]

As we're a small server we're relying on the support of our members, but giving admin perms to non-staff folks puts the server in a vulnerable point.

Adding an option where anybody can gift a server with a subscription from their own Tatsu account without getting admin perks would benefit both Tatsu and tatsu servers and their users, because

• 99% of people are hesitant to/wouldn't  gift us sub because they just don't want to be in a staff position for any short of the time, and

• we have to restrict the sub gifting for the oldest and most active members only, to avoid admin permission abuse

If these issues could cease with the option of gifting then more and more people would buy subs.
