Subject: [PATCH 1/2] Add blueMSX core to the build system

- Core entry in cores.json with 11 supported extensions, mouse
  and keyboard support, save state compatibility (SRM).
- Build hook packages the Machines/ and Databases/ directories
  containing freely redistributable C-BIOS ROMs into the core
  .data archive so they are available at runtime without a
  separate BIOS download.

Subject: [PATCH 2/2] bluemsx: reduce INITIAL_MEMORY from 256MB to 64MB

Memory growth is still enabled, so it scales up if needed. The lower
starting point reduces memory pressure on mobile devices and low-end hardware.
