Fix #267

Moving all files to main folder.
Using Gradle to define, manage dependecies and build the project.
Upgraded Gradle wrapper.

Reviewed all database access.
Fixed some unclosed connections.
Refactored bad code.
Added tasks for future refactor.

If the character name is invalid, it simply won't find any matches.
Besides that, if the admin changes the CNAME_TEMPLATE property over time, this check *could* make the old characters, created before the changes, unsearchable, which is certainly not desired.

Implemented:
Favorite Board
Home Board
Homepage Board

Partially implemented:
Clan Board
Region Board

To be implemented:
Friends Board
Mail Board
Memo Board
