Proposed, and implemented, some enhancements (1Mb + 1Mb firmware, resizable jsvars size, ...)

@Wilberforce

I'm wondering if there is a better area for the saved code rather than the end of the application user Space?

• ESP_FLASH_MAX is reduced to have extra pages for code and wifi

• afaik, this is the same technic that is used now for ESPs

@Gordon

Also, with the flash map - I don't know if all 1MB is really needed at the moment?

• Me too, but there are only a few KB left and as there are still improvements in Espruino, how long would it last until it does not fit in anymore?

• Using "4MB:1024/1024" still offers additional 2MB flash space

Is it possible to calculate how many space is needed by save() in worst case?
