Major peakmeter rework: * Changed set/get functions for dbfs mode to bool type. * Removed performance setting, leaving (slightly adapted) high performance mode only. * Refresh rate is always 20 Hz now. * Readout doesn't do an extra (hidden) peek, should allow for slightly better clip detection. * Brought back high performance peakmeter for recording. Peakmeter stops hogging the CPU when the disk is spinning; this is enough to avoid the performance problem when saving data. * Optimisations, code cleanup and code policeing. * (iriver) Reduced CPU load of peakmeter by not calculating excessive overlaps. ** Bumped config block version, so save your settings before upgrading.
