Add bridge upgrade code for 1.2 -> 2.0
Like the vlan upgrade code this uses slot 38 to make sure it will not run on a 2.0 configuration.
This is blind coded and needs testing. Please help testing.

Since we still needed upgrade code for vlans from 1.2 to 2.0 I added the upgrade at spot number 39 which is just before the user manager upgrade code.
This should make sure that we won't accidentally try to convert a 2.0 install. Good thing we left some spots open!...

Revert mwexec back to exec. They are very different functions.
mwexec() has a mute flag which can be true or false, exec, returns a
array in the 2nd argument and the return code in the 3rd.
We require the output from the command.
