Allow incremental value to be written to quota proc file

As well as writing absolute numeric values to the quota file you
can also write numbers preceded by a + sign or a - sign
would increase the quota by 30
would increase the quota by negative 20 which is the same as decrease
by 20

would decrease the quota by 5
