Make simple search cap-insensitive by default

[andrew-morris]

Right now the search functionality is cap-sensitive. This makes sense when a user is providing a regex, but for simple/quick search, it makes more sense to make search terms cap-insensitive

Good idea, keep em coming! Just pushed this in eeb43df.

I had to revert the changes because regex wouldn't work with the way it was implemented. Still open to doing this but not sure it's possible without effecting regex.
