Use eval to evaluate string literals

[bouk]

There are a lot of string literal issues that seem to stem from incorrect string escaping. This PR uses eval to make sure we get the proper value.

awesome this has been a thorn in my eye for a while.

why eval, though, is there no other way?

[bouk]

JSON.parse would be another way, but then you have to translate single quotes to double quotes and such which is a pain. eval solves this quickly and easily
