NOTE: This was originally in ArmoryQt.py, but we really needed this to be

Yes, I realize that it's awkward that we have wltMap {WltID-->Wallet} but
we have a lboxList [Lbox0, Lbox1, ...]. I will have to standardize the
member names and lookup structures.
We have a script and want to show the user something useful about it.
We have a couple different display modes, since some formats are space-
constrained. For instance, the DlgConfirmSend dialog only has space
for 34 letters, as it was designed to be showing only an address string.
This is similar to self.getContribStr, but that method is more focused
on identifying participants of a multi-sig transaction. It almost
works here, but we need one that's more general.
Consider a 3-of-5 lockbox with ID Abcd1234z and label
"My long-term savings super-secure" and p2sh address 2m83zQr9981pmKnrSwa32
10 20 30 40 50 60 70
| | | | | | | |
256 Lockbox 3-of-5 "Long-term savings" (2m83zQr9981p...)
256 Lockbox 3-of-5 "Long-term savings" (Abcd1234z)
50 Lockbox 3-of-5 "Long-term sa..." (2m83zQr9981p...)
35 Lockbox 3-of-5 "Long-term savings"
32 Lockbox 3-of-5 "Long-term sa..."
256 Wallet "LabelLabelLabelLabelLabelLabel" (1j93CnrAA3xn...)
256 Wallet "LabelLabelLabelLabelLabelLabel" (Abcd1234z)
50 Wallet "LabelLabelLa..." (1j93CnrAA3xn...)
35 Wallet "LabelLabelLa..."
So we will always show the type and the label (possibly truncated). If
we can show the ID or Addr (whichever is preferred) we will do so, otherwise
it gets left out. If our truncation leaves the string too short, we
usually try to add back in a few chars. It's not perfect, but it seems to
work reliably.
The doBold arg indicates that we want to add html bold tags around the
first N parts of the return. This is applied after the length calculations
are performed, as bolding will have a very small impact on width
