HDX/AV: log message overhead when in faster modes

[jteresco]

It looks like oneAction is saving log messages and building the hover HTML for past logs every time, even when log messages are not being displayed.

Questions:

• Can we skip all of those when running at speeds when the logging is not displayed?
• Is there enough benefit to displaying the logs by default even at slower speeds?
• Is there enough benefit to displaying the logs at all in terms of space in the AVCP?

Edited log messages in order to only be created and displayed on slower speeds

Remaining to do: set a boolean when speed changes to determine logging status, simplifying the conditions.
