Title: Don't execute commands with --exec by default

tpp's --exec feature is potentially a security risk when using with
presentations from untrusted sources. (Originally reported against tpp
in Debian at http://bugs.debian.org/706644)

This commit disables execution of --exec parameters by default and
adds an option -x to reenable the --exec feature only on explicit
request.
