Add slash command, TLO, and fix crash

• Updated Version (i kinda don't like this month/date thing

• Added ${PortalSetter} and members: Version, Step, InProgress. -- Version is just the version # -- Step is what Step you're on in the portal setter routine -- InProgress would be true any time you are on step1 or greater --- on pulse would kick you back to step 0 if you were not near the portal person etc.

• Fixed crash due to portalsetter settings panel not being removed on shutdown plugin
