Slightly tweak error when unable to bind port

A slight improvement over 2d2d8fae3d8bc4e82dc631d93c6e19f954bbee04 -- we don't know that it's the daemon, it could be the GUI.
AddToWallet implies BindWallet

Now that AddToWallet is called when loading transactions from the
wallet database, BindWallet can be integrated into that and does not
need to be an extra step.

Leaves behaviour unchanged, but makes the
fFromLoadWallet/!fFromLoadWallet paths in AddToWallet a bit more
symmetric.
Also switch the (unused) verification code to low-s instead of even-s.

a81cd968 introduced a malleability breaker for signatures
(using an even value for S). In e0e14e43 this was changed to
the lower of two potential values, rather than the even one.
Only the signing code was changed though, the (for now unused)
verification code wasn't adapted.

Add a "relayfee" field to getinfo.

This shows the minimum relay fee for non-free transactions in btc/kb.

The armory developers requested this so that they can prevent users from
 creating transactions that not even their local bitcoind will relay.

This also slightly reorders the getinfo output so that the fee related
 lines are grouped and changes the help text to reflect that the units
 are btc/kb.
qt: Show also value for options overridden on command line

Currently only the name of the option is shown for GUI options
overridden by command line (or configuration file). This commit
adds the value of the options as well, which is useful for
troubleshooting.
