[0.4.0-Alpha] Add Input Parsing Methods back with UTF-8 Support

[M-griffin]

SDL Input translates all input to UTF-8 automatically. We need UTF-8 aware string, parsing, and input methods.

Since we removed boost, all previous methods used in Obv/2 XRM need to be reworked.

1. Add new mini support for UTF-8 basic's for count chars, then parsing strings.
2. Move over and rework methods so we can update the dialing directory add input fields for
   a. configuration
   b. ssh login / password
   c. irc text and command input
   d. much more.

Added code for Utfcpp project
https://github.com/nemtrif/utfcpp

All added unit tests copied over from Obv/2 XRM to test the results of refactoring the code.
Unit tests are now all passing with updated i/o methods. in the 0.4.0 Alpha Branch. Can now start work on update the getline method for irc. This will need some rework for extended input and scrolling left and right in-line.
