Add VACATION :seconds support

[Дилян Палаузов]

Post scriptum:

Also sieve/interp.c:sieve_listextensions(sieve_interp_t *i) has to be 
fixed, so that it includes "vacation-seconds" in its return value.  The 
result of sieve_listextensions, including "vacation-seconds", is printed 
by timsieved's CAPABILITY command.

Extending sieve_listextensions() probably requires adding 
"vacation-seconds" in "sieve_extensions" in lib/imapoptions.
