Modifying default cache configuration, and adding an #ifdef to allow for a

current default configuration.
Description of Changes:
- increasing maximum cache size from 16MB to 32MB
- increasing maximum entry size from 10MB to 32MB
- decreasing min_clean_fraction from 0.3 to 0.01 in serial case
- increasing flash_multiple from 1.0 to 1.4 in serial case
