Implement Inventory Limitations

[Gvin]

There are 2 types of inventory limitations in game and they behave differently for player inventory and storage inventory.

For player inventory there are Weight and Capacity limitations.
Weight limits total items weight that player can carry.
Capacity limits amount of big items that player can carry (you can't carry lots of Logs in your bare hands even if you are strong enough).
In case any of if these limits is exceeded the player can't perform actions in current location (except for checking ground) and move to another location. He need to drop some items to the ground before any movements are done.

For storage inventory there is only Capacity limitation.
The player should not be able to put any items in the storage inventory if this would exceed inventory's max capacity.
