Silent sustain spam

[Hirumakai]

In IRC, we (edge2054, tiger_eye, myself) were discussing the practice of having the player's log be spammed with messages that every sustain has been turned off and then on with level up.

In addition, my rework of the Arcane Blade class has led to a few cases where some sustains need to be cycled off then on to pick up what the status of other sustains being up, which also leads to a fair bit of log messages.

These messages might be considered undesirable as they are more behind the scene machinery than actual in game need to know knowledge. One way this could be dealt with, is modify the forceUseTalent function to be able to take a silent flag, which it can eventually pass on to the preUseTalent function, which does all the activate/deactivate log message - and is already designed to take a silent flag.

Thoughts?

Sounds fine to me
