[EXPORT] Fixed missing data in PICO-8 export and Travis release:

- fixed PICO-8 export script not taking data BGM and data runtime into account
- PICO-8 export also puts png and web exports in proper folders, ready for zipping
- fixed Travis release not exporting data BGM cartridge with the rest (preventing reload of Angel Island BGM)
