This reimplements warnings that CheckTilePermissions previously had. It
defaults to on because every single call currently in TShock expects it
to be on.
This moves ice tile placement and processing from
TShock.CheckTilePermissions to TSPlayer in the form of the new boolean
'HasModifiedIceSuccessfully.' This is such a stupid thing we have to
track, but we have to track it.
Previously, we duplicated all of the check permission code and inserted
special ice code paths. This duplicated a ton of code for little gain.
The result of moving everything is that the control flow is easier to
follow.
In Terraria ice tiles are placed and melt on a timer so it's necessary
to track them being placed and removed to permit tile events that would
otherwise be blocked due to region checks and stuff. They're usually
fairly harmless blocks, and without this code, ice wouldn't work
properly. It's not ideal for this to be in TShock at all.
TShock.CheckTilePermission(ply, x, y, paint) has been replaced with
TSPlayer.HasPaintPermission and TSPlayer.HasBuildPermission
respectively. These two methods dramatically simplify the logic required
to process build permissions.
Still todo after this commit:
1. Implement warnings for when a player fails a permission check on
build. This is probably going to be accomplished by a default argument
to the HasBuildPermission signature.
2. Create a variant that checks for ice tile permission and use like
HasPaintPermission() so as to remove the other
TShock.CheckTilePermission method.
Annoyingly, all of the existing methods that start with Check seem to
"check" if they player _doesn't_ have permission (true = no permission),
which makes nearly every call negative.
This addresses feedback from @QuiCM and @ijwu, who pointed out that C#
allows you to specify the arguments that go into a call during
invocation, which dramatically improves readability.
TShock.CheckRangePermission is now TSPlayer.IsInRange, but the most
important thing is that this method returns the opposite of what the
original did, so all of the calls that would go to it are now inverted.
Bonus: Introduces a new GetDataHandledEventArgs for use in events that
have players, data, and need to be handled.
I was originally going to modify GetDataHandlerArgs, but that comes from
the EventArgs class of args that isn't handled, and changing that to
extend HandledEventArgs would imply we care or check to see if those are
handled and we don't so we're stuck with this implementation for a
teenie tiny bit.

Only called in one method, the stack hack detection can move to
TSPlayer as it only ever operates on one player.
In a future commit, this will replace the stack hack detection
OnSecondUpdate() and also set the disabled flag if a player has
a hacked stack when called.
