Flash storage Module, any js type , web pages, css, js and images

Just to update this, there's now:

• The Storage Module built in to Espruino itself which allows you to save simple 'files' - and load them in a memoryArea-style way that doesn't use up RAM.
  
• Save to flash and modules as functions in the Web IDE, which automatically save your code direct to flash
  
  

These work on all platforms.
