New Multicommand execution. Execute multiple commands by putting them in multiple lines. (This currently generates long URLs that are limited by the browser, this will be improved in a future version -> Testing with Edge got me running ~ 20000 lines of commands, so it shouldn't be that big of a limiting factor... )

Added two new commands for the execution:

• A onetime delay with /&timeout [time], which waits before executing the next command.
• And a global delay from now on, which adds a delay after each command with /&setdelay [time]

-> [time] is in the two commands in milliseconds, so 500 would be half of a second!

Added an option to exclude lines that begin with #, this mimics the comment function in datapack functions.
