Lots of small improvements

We've spent the last couple of weeks in summer mode. Lots of refreshing vacation, travelling, and even some ☀️ here in Iceland. Now that we're returning to full steam, we're starting with a flurry of bug fixes and improvements.

We made 17 improvements to the flow of inviting players to campaigns, including:

• GMs can now assign a premade character to a player.
• Invite links now have information about campaigns, even if they are full.
• Logged-in users are no longer taken to the signup page as a part of invites.
• GMs can now remove players from Characters.
• The invite link header now updates the name of the GM if there is a change to the GM.

• Fixed an issue where the campaign name wouldn't leave the top bar after you left the campaign.
• Fixed issues were transferring campaign ownership would still leave the previous owner with magical powers.
• Fixed a thingy when your Avatar head would bounce every time you hit space. A ghost from a different feature in the making.
