RuntimeStats: remove Timer functions
renamed: RuntimeStats.pm -> Views/CLI/idGamesDbDump.pm

- New module will hold methods relating to the CLI view for
  idgames_db_dump
Timer: close #111; refactor methods to accept 'name' param

- Shorten the 'start' and 'stop' method names
- All methods now require a 'name' parameter
- The 'stop' method requires that a corresponding 'start' timer has
  already been called
- The 'time_value_difference' method requires that both 'start' and
  'stop' were called previously
Timer: close #113; add delete() method
Timer: close #112; added POD
t/30-Timer.t: added tests for Timer object
idgames_db_dump: close #110; refactored Timer and CLI view modules
[JSON/XML]Parser: use idGamesFile module for File objects
schemas: use 'key' instead of 'id' for files

- Added a 'file_actions' table, for recording timestamps of different
  events like 'create' and 'update'
