Adds placeholders for phase block listing #385

[tastybento]

Adds two new placeholders that list the names of the blocks that can occur in the phase. One placeholder is for the user's island and the other is for the visited island.

• %aoneblock_my_island_phase_block_list%
• %aoneblock_visited_island_phase_block_list%

The names are prettified versions of the Bukkit Material, or the name given by the LangUtils plugin, which can hook into BentoBox.

Format of the output can be customized in the locale file in the placeholders section:

 placeholders:
     infinite: Infinite
     block-list-format: |
       &7- &e [name]

The default produces a (long) list of materials with one on each line, as requested by the author of #385. Alternatively, they can be put onto a single line like this:

  placeholders:
    infinite: Infinite
    block-list-format: '&e [name],'

The tailing comma will be removed from the list automatically.
