characters dialog should not include:
#
[
]

dialog format (angled brackets should not actually be in the file, but square brackets should):

So far, every the npc says and all responses should be in one line. Support for multiline stuff
will probably be added later.

If a response should end the dialog, the line should say [NULL]

Possible triggers are restoring the player's health, giving him an item, etc.
All triggers that are not identical should have different numbers. The actual effects are hardcoded.
If a response has no associated trigger, leave that line out.

#<num>
<text the npc says>

[<num this response links to>]
%<number of trigger associated with this response>
<possible response #1>

[<num this response links to>]
%<number of trigger associated with this response>
<possible response #2>

[<num this response links to>]
%<number of trigger associated with this response>
<posible response #3>

#<num>
<text the npc says>
