Convert 5e Monster Token should load default macros.

Is your feature request related to a problem? Please describe.
Converting 5e macro tokens enables the standard Simple5e macros, but leaves it up to the GM to actually import these macros - which is annoying.

Describe the solution you'd like
Instead, macros should be optionally loaded onto the token. They can be loaded from the Standard Token, or from any Standard NPC type token/solution from #33 to conserve GM secrecy for rolling.
