2.10-rc1

First candidate build for the upcoming 2.10 release. Sorry for the wait.
Please help us check for regressions, especially in TAStudio and the rest of the TASing workflow, and in Lua. Remember: if it's not reported then it won't be fixed! Report bugs here or on Discord, TASVideos, or Reddit.

2.10 includes a fully-functional Encore (Citra) and ChannelFHawk. We also have 2 new WIP cores, PUAE and Stella, as well as updated Genplus-gx and QuickNES, and regular updates for several other cores.

edit: quickerNES won't work on most Windows PCs. You should be able to drop this copy into the dll folder.

A changelog listing all the bugfixes and improvements will come later, but for now you can check the resolved issues and commit history.
