HackStudio: Add evaluate expression popup to debugger

Browse source 
This implements a dialog that can be used to evaluate a JS expression
in the HackStudio's Debugger context. It also implements simple
C++ Variable <-> JS Value conversion, allowing for JS expressions
to read/write variables in the debugger scope.

Currently, C++ structs are mapped to JS objects by way of a JS proxy,
however this leads to issues when printing, so this will be changed
in a later commit.
