Make cache type selectable based on config value
Provie a mechanism to specify cache type from NONE, APC, or MEMCACHE based on a config variable. If MEMCACHE type is selected, a list of servers can be specified to provide multiserver support. Note that php-memcaced is required for MEMCACHE support. Lukas: Minor commenting style fixes. Signed-off-by: Lukas Fleischer <archlinux@cryptocrack.de>
