Added Database Managment command, Small improvements [2.3.0-SNAPSHOT]

- Added database managment command:
- Copy & Overwrite data from one database to another (moving from one db
to another)
- Copy & Combine data from one database to another (in case both were
used)
- Remove player's data from the active database
- Clear a database
- Check what database is in use, also on info command. Also now told on
enable.
- Hotswap to another database, reloads plugin with new database set in
config

- Reload command now restarts the plugin, DOES NOT LOAD NEWLY PLACED JAR
- Fixed typo in search command arguments

- Import command for OnTime in PlanLite
- Recent Players
- Lists of players
- Location heatmap
- Investigate Bungee support possibility
- Make Analysis.java readable
- Move the data combine methods from MiscUtils to new class
- Database Cleaning
- Change database initiation message to include "connection"
- If you feel like it make better html
