I18n: make more parts of the UI translatable

- "Name collisions" label in mesh properties
- "Threshold" labels in Vertex Weight Edit modifier
- "Particle System" label in Particle Instance modifier
- Slot number in the Shader Editor

- Status bar keymap items during modal operations:
  add TIP_() macro to status bar interface template

- On dumping messages, sort preset files so their messages are stable
  between runs
