Title: add functions for performance stats

suggested replacements for old profile() function

elapsed() = time elapsed since f3 loaded;
default to return with label showing micro | milli | seconds
note range boundary, above 0.09 uses seconds, easier to read .33 seconds than 330 milliseconds

memory() = memory used by php script;
default to peak memory, default to return with label showing KB | MB
