Make texture searching happen manually

[LDinos]

So far I have noticed that sometimes, while I am writing for a texture to search, I happen to stop typing for a bit and hammer++ is already searching accoding to my filters and I cannot stop it. I wonder if it's possible to make sure the user has typed the filter and then search the texture, most probably by pressing enter. Perhaps a tickbox that disables "auto search while typing" or something :)
