Facet expiration flag

Problem:

For performance reason a facet may cache the data in browser's memory. There should be a flag to indicate whether a facet has expired and should be refreshed. The expired flag could be set by these events:

 1) any update operation
 2) changing search filter in search facet
 3) switching page in a multi-paged search/association facet
 4) switching direct/indirect view in association facet
 5) facet expiration time
A facet should be able to use these methods to refresh itself:
 6) on demand: an expired facet should be refreshed when a user opens it.
 7) automatic: an open facet should automatically refresh itself when it expires.

Solution:

This patch solves cases: #2, #3, #5, #6. Case #4 works without any change. Case #1 will be solved later. Case #7 is deffered.

Default expiration timeout was set to 10 minutes.

In this patch are also updated facet.needs_update methods to reflect changes in containing facets.
