* Add a workflow which builds candidate release artifacts for Linux, OSX, & Windows
* Cache wxWidgets builds for build speed and to not put load on their servers
* Cache download of inno installer to avoid putting load on their servers
* Create a development release
* Fixed compiler error that shows up on OSX CD machines
