Isn't saved, as in "isn't written to the decode_as_entries file", or is saved but doesn't work?

For uint dissector tables, GTK+ was writing out the value in decimal, regardless of the base of the value for the table; Qt was writing it out in hex if the base for the value was hex.

The code to *read* the tables assumed decimal, and read a hex value as 0, because it was using atoi().  I fixed it to use strtol() with a base argument of 0 (so that a number beginning with 0x or 0X is treated as hex), and to check that that the string was a valid number and the value was in the range 0 -> UINT_MAX and report lines where it isn't.

This fixes it to the extent that the saved values work; I backported that fix to the 1.12 branch.

However, if I change it in Qt, the change doesn't take effect until I quit and restart Wireshark, so there's another bug hiding there.
