Only imply recent minion skill use on non-permanent minions

[Lilylicious]

Fixes #669

Description of the problem being solved:

All minion skills implied a recent use of a minion skill if they were set as primary. This adds a flag to permanent minions and excludes them from the implication. You can still use the config checkbox to enable these interactions on non-permanent minions.

Steps taken to verify a working solution:

• Allocated Enduring Bond, equipped Summon Holy Relic (permanent) and Summon Raging Spirits
• Deallocating Enduring Bond without the config checked does not affect Summon Holy Relic DPS but does affect Summon Raging Spirits DPS
• Selecting the config checkbox for recent minion use changes the DPS of Summon Holy Relic but not Summon Raging Spirits when Enduring Bond is allocated
