Espruino 2v10

Espruino 2v10 has just been released.

Some huge changes this time!

The biggest one is the merge of the experimental_compact_vars branch, which adds roughly 20% more JavaScript variables to most builds, within the same RAM footprint. Performance suffers by around 2% but for the vast majority of users the increased memory should be a massive benefit. More info here...

Other changes are...
