[Build 135] Session Time & Gaps

For non-Forex, please enable Session Times such that gap detection & filtering can be used.  Right now, session time is only for when trades can be placed.  Indicators and daily high/low/open/close are not calculated on the session time.  For example.  SPX has gaps all the time between closed[1] and opend[0], but in @ES you won't find very many.  Enabling proper session time for @ES would allow gap detection to more closely reflect what SPX is doing on market open/close.
