Added multi-command syntax and delayed-command syntax. More details can be seen on the github page: https://github.com/konsolas/ConditionalCommands

Still compatible with legacy syntax.

Added two new placeholders:

• -perm:<permission>- (1 if the player has the permission, 0 otherwise)
• -aacvl:<check name>- (if AAC is installed)

Example usage can be seen on the github page.
