Koder doesn't like big files

[humdingerb]

I have an almost 2 MiB big "hosts" file that Koder doesn't deal well with. It takes a second or two to open and then editing or even scrolling or placing the cursor pegs one core in the window thread.

I can upload the hosts file, if needed.

Do you have whitespace highlight enabled? Is it better if you disable it?

[humdingerb]

Yep, that's exactly it. Without highlighting trailing whitespace, editing and scrolling is fast as ever.

Dupe of #47.
