save local program does not correctly save programs with template literals
If the program contains template literals, i.e. multiline strings defined with backticks like this:
mod.text.value = `place your
notes here
`
JSON.stringify creates this
mod.text.value = 'place your \nnotes here\n'\nnotes here\n`
Which when you load back the program renders like:
mod.text.value = 'place your
notes here
'
notes here
`
And hence not loading properly the page.
