Change creeper max fuse and no damage ticks to timespan

[kiip1]

Description

Change creeper max fuse and no damage ticks from amount of ticks to timespan, although the former was logical due to it being the property in Bukkit, it doesn't align with the rest of Skript's syntax, therefore it should be timespan instead.

This will be a breaking change for users without sufficient justification. You could support the original format as an additional pattern.

This syntax can also support a primed tnt in the future, so it's a scuffed addition but we have to deal with it now.

I like this syntax change.
