Feature Request: Quickened Spell Metamagic Handling

[trioderegion]

from discord user JustinTheDM#5827

Would be kinda neat if the sorceror class came with metamagic 'attributes'
Where using a metamagic effect sets the attribute to true, and the next spell cast could "consume" that true, adjust the effect, and set the flag back to false
Something like @classes.sorceror.flags.extended, @classes.sorceror.flags.twinned, etc
A little extra work could even include "legality" checking and throw an error if you try to do something like twinned fireball

I would like to reduce the scope of this issue to fit into the 2.0 release. As a survey of the metamagic options, the following are the ones most appropriate to 5e Helpers (in order of importance):

1. Quickened Spell -- change action spell to bonus action. This interacts with the new action management system and would be a good starting point.
2. Transmuted Spell -- change elemental damage type to another elemental damage type. Has no impact unless you are using damage automation and is therefor very low priority.

In summation, I would like to reduce the scope of this feature request to "Implement Quickened Spell Metamagic"

I believe Crymic or theRipper on discord has handling of transmuted spell which might be a good reference point

Returning to the backburner. More class specific functionality will be coming soon (ish).
