Event String names should be consistently cased

[dsparacio]

Some history
Michael and My intention was CoreEvents.js are all internal client events that a player will not need access to, if we want something to be documented and external it can be moved from CoreEvnets to MediaPlayerEvents with no other changes. This is because all events are pushed into Events.js which the client uses internally. In addition events marked with prefix string "public_" E.g. ProtectionEvents.js, this will be programmatically moved to MediaPlayerEvents as well so you can access them in one place at the player level.

We need to pick one style and apply. camelCased VS lowercased

Do we have any opinion on the style used? I can see arguments for either direction.

cameCase is a bit easier to read and uderstand.
lowercased is more in line with native browser events.

Personally I lean more towards camelCase because it can take a second or two to stare at the lowercased string and figure out exactly what is being said, where camelCase is much easier to read quickly.

There are more camalCased and easier to read so all strings have been converted. I also moved a few events from Core to MediaPlayer which will not affect any internal code or existing players.
