Asset Bundler GUI (#427)

The AssetBundler is a new ToolsApplication that allows users to work through the entire Asset Bundling process without ever touching a command line.

* Integrating github/AssetBundler through commit 1d65018

* Asset Bundler bug fixes: platform initialization and GUI styling (#5)

* fixed enabled platform initialization

* fixed the cached engine root. This fixed some of my Seeds tab data issues. The default Engine Seed List appeared, and was able to display the contents on screen.

* updated my notes of active bugs

* changed some casing in various include lines to hopefully fix my linux build

* another include fix for linux

* AssetBundler GUI is now compiling on Mac

* removed some things off of my todo list because the mac build fix actually fixed the visuals! everything's the right color again

* removed the word Lumberyard from the bundler

* Asset bundler bug fixes - Bundles, Gems, and Tests (#9)

* Fixed the Bundle loading and generation problem. Turned out to be a FileWatcher issue.

* turns out gem loading wasn't broken, there were just no existing SeedListFiles for any of the gems loaded by the AutomatedTesting project. I added a default SeedListFile for the PrimitiveAssets Gem.

* fixed some failing AssetBundler Gem tests

* Misunderstood the need to have default seed lists for asset-only gems. removing the previously created seed list file

* Asset bundler bug fixes: Seeds Tab display issues and _dependencies.xml loading (#10)

* Fixed the Project Source column in the Seeds tab

* The AssetBundler will no longer attempt to copy a template version of the ProjectName_dependencies.xml file into your active project. However, it will throw an error if you do not have one. A follow-up ticket has been cut to address this issue.

* updated the AssetBundler icon. This one matches the current style guides

* PR feedback: pass a const ref instead of a value

* PR feedback: safer conversion from a string_view to a QString
