Disabling Javascript breaks some browser functionality

[mykhal]

Current Behavior: Disabling Javascript breaks the Luakit settings page and some other functionality (e.g. bookmarks adding).

Desired Behavior: Disabling Javascript should not affect browser UI functionality itself.

How can we reproduce it (step by step):

1. Disable Javascript (:settings, uncheck webview.enable_javascript checkbox).
2. Restart Luakit browser.
3. Go to some web page and try to add a bookmark (B). Bookmarks page with filled popup dialog appears, but on Save, empty page appears (possibly with already existing bookmarks gone), and the bookmark is not saved. (Neither :bookmark URL works, as it triggers the same UI.)
4. Try to enable Javascript again (the checkbox label does not change to green "Enabled", which might not be noticed at this time). After browser restart, Javascript is still disabled. User realizes that the settings UI is practically defunct. (:set webview.enable_javascript true +restart works.)
