Bugs corrected

[Emmanuel <e allaud wanadoo fr>]

	Hi all,
3 patchs attached correcting bugs (perhaps already submitted but I had 
no answer):
-in ./libbalsa/address-entry.c : misplacement of the cursor (at end 
instead of beginning)
-in ./libbalsa/filter-funcs.c : missing initialization of filter field
-./libbalsa/filter-private.h : misspelled field of filter struct in 
macros
