Commands:

• /cm reload properties

Placeholders for PAPI:

• %catamines_countdown_<mine> is now the new formatted countdown
• %catamines_remainingseconds_<mine> is now just the seconds

Bug fixes:

• Reset message was all messed up in the last version

It's a little hard to explain what happened in this update, but I will try my best to explain it so you can see why it is so useful.
First of all, I changed the countdown formatting. Now, the remaining time will be displayed like this using the internal %formattedseconds% or %catamines_countdown_<mine> placeholder with papi:
"hh:mm:ss"

Every mines starting value for warnmessage, resetmessage, hotbarmessage has now a default value: "default". Every mine that you create from now on will have this value, which translates into whatever you specified in the new default_properties.yml file, which means if you created a lot of mines but you want to change one of those properties for all of them, all you have to do is change it in the file, and run /cm reload properties.
