[Commands] #reload Command Overhaul. (#2162)

* [Commands] #reload Command Overhaul.
- Consolidated #reloadaa, #reloadallrules, #reloadcontentflags, #reloademote, #reloadlevelmods, #reloadmerchants, #reloadperlexportsettings, #reloadqst, #reloadstatic, #reloadtitles, #relaodtraps, #reloadworld, and #reloadzps in to one command.
- #reload has 15 different sub commands you may use, including Log Settings and Tasks reloading.
- All the reload commands are a part of the Developer Tools Menu messages now, as well as part of the documentation.
- Fixes the commands that weren't actually sending their packet to zone server to globally reload stuff.
- Added Variables table reloading to command.

* Consistency.

* Hot reload.

* Final big push.
