Api: For admins (us) bypass the limit of plugins that can be created

[TouchySpidey]

When one of us is creating a plugin, do not check for the number limit.
The following two changes should do it
In PluginController.cs:GetPlugins(), set result.MaxPlugins to 9999
In PluginRepository.cs:HasReachedPluginQuota(), return 9999

When checking whether to return 9999 or act normally, the whitelist should probably check for emails instead of userids, but it's your discretion

Usually i write issues requesting the desired outcome but not the details of how to achieve that as it could be not the most obvious one the right one.

So if I have not done the right research and I'm sure 100% that's what do be done I try not to write a proper solution.
