Move bronann's father sprite out when not in his house anymore.

It was still possible to speak with him when pushing F around the fireplace.
Replaced the lua_strlen calls() by lua_rawlen() ones if compiling against lua 5.2.

Let's hope it will help with issue #80.
Drastically simplified the Quest Log system.

I removed the unique quest key from the quest log entries
and made the completion events be part of the quests.lua file.

I also lighten the MenuView::Update() and Draw() calls, making
the check for completion only done when opening the quest list window
for the first time.

I also moved the completion check into the global manager and removed
redundant or used once functions.

Finally, I added a small green check in front of completed quests.
Added the Minor Elixir to Flora's Shop and make it able to revive
a character.

This should take care of the problem with players stuck in the middle
of the dungeon when one team mate dies.
fixed with upstream/master changes
bug fix and slight item menu change

bug fix:
+ when using an item and causing that item category to "run out", a second
press of the use button (default f) would cause the game to crash.
As described in #99

this fix also addresses another issue by changing (slightly) how the items
menu operates:

+ When an item is used or equiped, we return back to the item list. When a
list is empty due to the previously mentioned "use/equip", we now return
back up to the category selection. If there are no more items in the
inventory, we are returned all the way back up to the Use/Equip/Remove
selection stage. In essence, it acts as a "stack unwind."

This fixes the bug related to this issue, as well as an ticketed bug/issue
whereby once an item ran out, the list automatically moved to the next
item in the list without warning. this meant that you could accidently use
up items with rapid button presses and not have a "one-button" cushion.
Fixed two english typos found by Daphron.
Improved a bit battle finish level ups display.

- Changed the 'XP:' text to XP left:' to make it less confusing.
- Added '+' in front of the stats that being upgraded at level ups.

Thanks to Daphron's feed-back about this.
Only fade a music in when it was loaded and can play successfully.

Prevents a crash with missing music.

Closes #100
Synced luabind to the 0.9 branch of the official repository.

This should provide a working lua 5.2 support.
Added a new battle music from Mumu (OGA)
Fix a compilation warning
Made valyria tear's binaries install in the bin/ folder.

the code already had a simple way to change the directory to the package
data, so no more hacks were needed.

Valyria Tear should be packageable now.
