configurable row count for tables in console

Number of rows in tables is hardcoded to 8 ("... new DefaultCellTable<.....>(8);")

This can be considered to be a low value for large sets (e.g. imagine tens or hundreds of bundles in OSGi subsystem).

The value should be configurable by the user (e.g. combobox with predefined values - 10, 25, 50, 100)
