[mod] Extended skills and awards

[Csimbi]

No TXT files this time; I did not have time to write them up.

One extends the skill levels to 5, the other extends the award levels to 5.
The award mod also fixes this bug:
"Guardian" award - While the hint appearing above this award says that this award gives resistance to all types of damage, it actually does not give any resistance to 'glacial' and 'astral' damage.

Just put the appropriate kfs file in the <King's Bounty>\SESSIONS\ADDON directory and you're done.

In case you use other mods, these are the ones you need to watch for conflicts:
Extended skills modifies these files:
- skills.txt

Extended awards modifies these files:
- addon_rewards.lua
- medals.txt

Since I cannot possibly test all these in-game, feedback on balancing would be appreciated.
