test GUI

fixed compile issues on many platforms, wallets will now save properly in CLI ( no .wallet), GUI had mixin logic adjusted and decimals places corrected.

Ui is a little more explanatory, with tooltips for GUI wallet

pretty sure mac users will need http://qtmirror.ics.com/pub/qtproject/archive/qt/5.8/5.8.0/qt-opensource-mac-x64-clang-5.8.0.dmg

QTPenny.zip is mac GUI, qtprnnyWindows is win GUI
