Challenge condition supports PlaceholderAPI

[Noogear]

Is your feature request related to a problem?

PlaceholderAPI support

Describe the solution you'd like.

Add a new condition for challenge. It is used to determine whether PAPI meets the conditions.
Required conditions:

equals
<> (not equal)
<=
>=
<
>
=

For example, you can use %aoneblock_my_island_lifetime_count% >= 1000 to check wether pass the challenge.

Describe alternatives you've considered.

This one is more universal, isn't it?
