Completely rewrote ComponentGrid to use shared pointers, have support for
borders, work better with nested components, and generally suck less.
Split the scraper screen into a "ScraperSearchComponent" so it can be reused in other menus (what could this possibly mean for the future?!).
Re-designed the ScraperSearchComponent to fit UI concepts.
Added the ability to put a row of buttons at the bottom of a MenuComponent.
Redid GuiMetaDataEd to use a MenuComponent instead of ComponentGrid.
Redid GuiGameScraper to use a ComponentGrid containing a ScraperSearchComponent.
Fixed Renderer::pushClipRect not clipping new rects to be within the bounds of the existing clipRect stack.
A ton of little fixes that I forgot to mention.
It's a good thing I'm the only developer currently, or I would have to actually break this into multiple commits.
