[enh] bind heritage in config panel

[zamentur]

The problem

When we create config panel, sometimes all a section or a panel is bound to a same config file. Always copy the bind property with the config file path is so much verbose !

Solution

Implements a sort of heritage between panel section and params, example:

[main]
name = ""
bind = ":__INSTALL_DIR__/public/organization.properties"
  
  [main.section_1]
  name = "General"
    [main.section_1.foo]
    bind = "toto:" # -> "toto:__INSTALL_DIR__/public/organization.properties"
    [main.section_1.bar]
    # Pas de bind à ce niveau -> ":__INSTALL_DIR__/public/organization.properties"
    [main.section_1.aaa]
    bind = "settings" # -> "settings"
    [main.section_1.zzz]
    bind = "null" # -> "null"
    [main.section_1.plop]
    bind = "plop()" # -> "plop()"

  [main.section_2]
  name = "Advanced"
  bind = "advanced>:" # -> "advanced>:__INSTALL_DIR__/public/organization.properties"
    [main.section_2.foo_2]
    bind = "foo:" # -> "advanced>foo:__INSTALL_DIR__/public/organization.properties"
    [main.section_2.bar_2]
    bind = "somewhere>bar:" # -> "somewhere>bar:__INSTALL_DIR__/public/organization.properties"
