Plugins Voice Commander

I fixed a bug where if you disabled and then re-enabled the plugin, it would stop listening (until the plugin was loaded again). It will now start listening again every time you re-enable the plugin.

I optimized the keyword refreshing, primarily so as to avoid rebuilding and restarting the keyword recognizer when no changes to the keywords are detected. This means you may now typically enable the periodic refresh and use a faster rate, which is now much less likely to cause missed recognition due to it rebuilding/restarting while you were speaking.

• Upon request I added a manual refresh triggering option: "Refresh Keywords Now"
• I added a periodic refresh option, so you can have it refresh keywords every few seconds. Note that for a short time after it refreshes, it can't recognize input, and if it refreshes while you're speaking it won't recognize that. So, it's best to either use a longer refresh rate to minimize that (hence the limited range on the rate), or rely on the manual triggering and refreshing after each spoken action invoke.
• I replaced the demo scene to avoid the unofficial dependencies on my other resource (Cheerleader Costume), simplifying it considerably, as it's only meant to briefly showcase how the plugin works.
