v 18.8.0 Breakin' and fixin'

The long awaited 18.8 version of Mycroft-core. A couple of bigger changes to the API was included.

The following non-compatible changes has been included:

• enclosure api separated from enclosure logic, this will make it easier to create thirdparty enclosures and support future mycroft enclosures. #1767, #1760
• a couple of deprecated util functions were removed along with the deprecated DeviceApi methods find_* #1752, #1756
• Booleans and Numbers in websettings are now casted to the correct python type
• update to more modern python module structure, all main.py files were removed.
• remove depreciated ScheduledSkill #1731
• MycroftSkill.get_response announcement parameter has been removed (the dialog parameter now supports strings as well so it has become redundant) #1758

locale directory #1764, #1773

Skill vocab, dialogs and regexes can now be placed in the SKILL/locale

Simple audio service #1761, #1774

Replace the separate mpg123 and ogg123 with a "simple" audio service using simple command line tools to play mp3, ogg and wav files.

Emitter/ws -> bus #1757

The messagebus connection instances has been renamed to "bus". The old MycroftSkill.emitter is still available for backwards compatibility but will be removed for 19.02.
