/**
* This method is a simplification of loadPreferences()
* It is created mostly because of the performance reasons.
* The method loads given preferences in given account only.
*
* It doesn't take into account any preferences cascading so
* before using this method be sure that the performance you are
* looking for can't cascade (this is often the case for the preferences
* which are available only in given accounts).
*
* This method uses by default static in-memory caching to improve
* the speed of reading in the preferences - this is helpful in maintenance
* where admin preferences can be read in many places and many times.
