[BUG] `setvar myVar "text"` casts as `int` and expressions fail on it

Another bug resulting from this: #55

The number you see here is the max value of an unsigned integer, so the issue is not that it converts a string to an integer, it tries to convert it to a serial and when that doesn't work uses the max number as a fallback (for some reason)
