Regex search / replace from cfg file

[genotrance]

The libsass wrapper requires manual edits as noted by @zacharycarter.

• c2nim doesn't like the paranthesis

Add something like searchregex to nimgen to allow search/replace with matching. Like: searchregex = "typedef struct (.?) \((.?)\);"

Wrong issue ID closed this by mistake.

This would be useful for future wrappers. I think it's a good idea to support and wouldn't be too hard to add. Literally just another section but with the value wrapped in re(). Might be a bit more complicated but probably not much.

Fixed in 0.3.1
