fixed some more items not working for creep-hero owners

fix to mjollnir for ld bear and broodmother talents

changed useless talents on some heroes, like talents that pierce debuff immunity (puck) or give true sight (clockwerk)

fixed LD's synergy giving 10x stats last level instead of 100%

HEROES
======================
- Lone Druid: Spirit Bear is now an innate ability. The Bear benefits from Lone Druid's Strength, Agility and Intellect.
- Lone Druid: Added new ability: Synergy. Synergy adds bonus max health, bonus attack damage to both Lone Druid and his Spirit Bear. Additionally, while Lone Druid and his Spirit Bear are both alive; any damage taken by one is shared by the other. The damage taken is percentual, the unit with the most max health will take the most damage. For example, if Lone Druid has 50k health, his Spirit Bear has 200k health and Lone Druid takes 10k damage, Lone Druid would instead take 2.5k damage and his Spirit Bear would take 7.5k. This shared damage is non-lethal. Damage taken and shared is considered before reductions.
- Silencer: Reworked Glaives of Wisdom to give Silencer Intelligence on hitting creeps. The Pure damage is now added directly to his attack damage, making it no longer count as spell damage. If a creep-hero dies while within 925 radius of Silencer, he permanently gains Intelligence. This works retroactively, not requiring the ability to be leveled.
- Silencer: Rescaled Glaives of Wisdom damage to account for losing spell amplification and Intelligence gain from the ability. Overall higher earlygame, lower lategame.
