#48 Behavior + Display of spells when hero lacks mana (0.71#69)

[Radu]

When hero does not have enough mana for some spells:

1. Behavior: We can still select them. Only when we try to cast them on the target creature nothing happens. L-click on them should actually do nothing (Spell Book should remain open).

2. Spell Book does not display differently the spells which are not available due to insufficient mana. See difference in H3 screenshot: [IMG]http://i4.photobucket.com/albums/y104/Zamolxis/VCMI/VCMI%2007/090620-H3Spells2.jpg[/IMG]
- Available (enough mana): Spell Name in light yellow, Level + Spell Points in (slightly grayed) white
- Not available (not enough mana): Spell Name in White, Level + Spell Points in Yellow (almost with a tint of orange)
