Adds a non-test mode (--showsql option) that displays the missing
sysprefs as sql inserts. Some sysprefs were missed from the syspref
file due to extra spaces in the insert : fixed. The test now checks if
there are at least as many sysprefs in the database as in the syspref
file (instead of checking for the exact number)
