removed high/med/low from kelondroRecords cache control.

Browse Source 
this was done because testing showed that cache-delete operations
slowed down record access most, even more that actual IO operations.
Cache-delete operations appeared when entries were shifted from low-priority
positions to high-priority positions. During a fill of x entries to a database,
x/2 delete situation happen which caused two or more delete operations.
removing the cache control means that these delete operations are not
necessary any more, but it is more difficult to decide which cache elements
shall be removed in case that the cache is full. There is not yet a stable
solution for this case, but the advantage of a faster cache is more important
that the flush problem.
