temporal queries via WFS

[Yewondwossen Assefa]

Tom,

 This end up to be setting the expression as It was a litteral 
expression instead of setting it using the back tics that indicates to 
mapserver to do time comparing (`[time_field]` ge `2004-10-12`). There 
is no detection right now to see if the filer parameters are time values 
or not. Not even sure how we should detect it. If we can find a way or 
logic to indicate that the value is a time, setting the filter is pretty 
easy.
