Provide LUA Debug Console feedback for user typing LUA string.

When the user explicitly types 'return expression[, expression]...' we convert
the result of the expressions to LLSD and format them into the LUA Debug
Console, which serves as a useful acknowledgment.

But until now, if the user neither invoked print() nor ran a 'return'
statement, the LUA Debug Console output remained empty. This could be a little
disconcerting: you click Execute, or press Enter, and apparently nothing
happens. You must either monitor viewer log output, or simply trust that the
Lua snippet ran.

When there are no 'return' results, at least emit 'ok'. But when the user is
entering a series of no-output commands, vary the 'ok' output by appending a
counter: 'ok 1', 'ok 2' etc.
