Remotery: Browser console optimisations
* Accumulate text in a string and assign as a whole to innerHTML (appending forces a reparse).
* Clip size of the log text to about 10k as the browser tends to become unresponsive at higher sizes.
* Only copy log text to the HTML node every half-second. This cuts CPU use down massively.
Remotery: Big stability update for stuff that uses Remotery at ridiculous update rates (i.e. not games)
* Allow multiple message types in the queue with variable payload directly after.
* Fix deadlock in message queue with overwriting the "not ready" marker unreliably.
* Remove the custom sample queue and place completed sample trees in the message queue, taking advantage of its discard behaviour when the queue becomes full.
* Move JSON buffer out of the thread sampler and into Remotery.
* Added the beginnings of a config section.
