first verison of layer name builder

1.5.3

- feat: quick-prefix for layer using pref separator
  - list editable in addon pref
  - add interface button above layers
- code: added environnement variable for prefix and separator:
  - `PREFIXES` : list of prefix (comma separated uppercase letters between 1 and 6 character, ex: 'AN,SP,L')
  - `SEPARATOR` : Separator character to determine prefixes, default is '_' (should not be a special regex character)
- UI: add addon prefs namespace ui-box in project settings
