UI: Multithreaded Updater (#2031)

Browse source 
* Use multiple threads to download different chunks of an update simultaneously. This reduces time to complete the download significantly.

* Remove dirty-flag check (for test purposes)

* Clean up updater code.

* Include fallback to single-threaded updater if mt fails

* Reduce connection count to 4.

* Improve fallback on error.
Correct issue where data was missing during download due to total build size not being cleanly divisble by the connection count.
Cleaned up unnecessary code.

* Add missing return statements

* Fix alignment

* Alignment

* More alignment

* Rely on content-range request instead of xml/json size property.

* Re-instate dirty checking and version checking to move into review stage.

* Address comments

* Address comments

* Comments

* Comments

* Final...?

* final final

* final final final nit

* Use Array.Copy as requested by rip

* Updated some names for clarity.

* Move addition into for loop (to shorten line width)

* Add missing semicolon -- forgot to stage :9
