First live demo

1. Add base proxy plugin to set common proxy plugin functions -
currently enables getting the proxyData data.
2. Create plugin for GetMediaLicenseLink - add event dispatching for
autoSelectSource in “setupSourcePlayer” - need to refactor
“autoSelectSource” so it will be possible to dispatch the event from
it, cause there are other places that call this function.
3. Add php files to support new module - TVPAPI - all plugins for
TVPAPI will be included in it.
4. Add proxy flavour assets handling - need to refactor for live
entries.
5. Add new lexer feature - maps.
