I've refactored and added FilterType.NONE and FilterType.ALL.  There is 
now only one instance of "12345" and "-12345".

Please see JIRA GEOT-916 and GEOT-848.  I haven't made any changes to 
what each SQLEncoder had defined as its Filter capabilities -- only 
*how* it is defined (in some cases there was a private 
filtercapabilities variable defined in the class, and the superclass 
method was obtaining a different variable -- so some differences may be 
present.  Justin pointed out that Postgis does not support BEYOND, so 
this has been removed. 

...now onto GEOT-917 (merge SQLEncoderPostgis and SQLEncoderPostgisGeos)

Cheers,
Cory.
