v1.4

• Blocks Nuke UI when active. This greatly improves usability when
  the weights are slow to load (e.g in heavy Nuke script, or slow
  home-dir access), as it prevents key-presses intended for
  tabtabtab from being handled by Nuke (possibly creating
  new/modifying nodes etc)
• Up/down arrow keys cycle correctly
• Indicator blocks now actually indicate node weights, instead of
  always being green. The blocks are also now narrower, which looks
  nicer
• Prevent vertical scrollbar (reduced number of shown items to 15)
• Node weights are loaded on every invokation, preventing
  overwriting of values with multiple Nuke instances
