Enhancement: Feels like cheating! ;)

 * up the memory limit (this is twice the size of our main code-base)
 * up "accelerated files" to cache more files
 * disable cli opcode cache
 * disable timestamp checking (we 'reload' on deploys)
 * remove revalidate frequency (we 'reload' on deploys)
 * up max wasted percentage

 * file override
 * optimization level
 * sane combination of save_comments and load_comments (maybe app specific)
