Typos
Added full support to obtaining skills through equipment.

The skills obtained are of course removed when unequiping, while
the permanent skills remain.

Those can be viewed both in the menu and in the shop modes.
(See the omni-sword for an extreme example.)

Closes #124.
Only save permanent skills or they'll be taken as is at next save load.
Fixed self-assignement case of operator= fpr AudioMemory objects.

Might fix certain crashes.
English fix of the Death spell description.
Tested also whether the global scripts could open before initializing the game.
Fixed a memleak when turning a skill into a permanent one.
Finished support for scenery sprites, such as the squirrels.

The scenery sprites are sprites that can collide with others themselves,
but the character and the enemies can't.
It is useful for little harmless things that make the maps more lively.
Fixed crash at battle end due to the lack of proper actor skill instance copy.

Fixes #178
Changed time and drunes to icons.
Made the clock a bit darker, less toonish.
Optimized a bit the code for object interaction.

This also definitely fix the second save point sometimes not responding.
Made the last squirrels be scenery sprites.

And remove some useless parameters in AddEnemy() functions while seeing it.
Ironed out a bit the inventory add/remove functions.

This avoid getting 0 count objects in the inventory in certain corner cases.
