Bugfix: Fixed 'slow' cgi programs and wrong timezone in cgi programs

CGI responses were getting held up before being passed to client, making CGI programs effectively unusable. Timezone was also wrong in cgi programs, due to a kind of bug in how glibc caches timezones that's incompatible with chroot.

Websockets, SSL Version control, Better Cache control

Initial websockets support added. SSL version control added. VPaths can now take arguments that alter their behavior. 'FileType' command controls compression and cache time for files matching an fnmatch/shell pattern. Performance improvements (especially for SSL/TLS). Session cookie authentication added. PAM session control added.
