Initial support for DynamicObject members

Since DynamicObject objects require a compiler, referenced
Microsoft.CSharp to do the compiling. For the time being, using
Dynamitey as a dependency since it provides the
Dynamic.InvokeGet(object, memberName) function, which otherwise would
require a large amount of additional work, which the Dynamitey.Dynamic
static class already provides. Perhaps the parts of Dynamitey that were
used could be imported into the Mustache# project in a later change.
This has been tested using DynamicObject objects that have members, but
I'm not sure yet how to interface this with any type of indexed
DynamicObjects, for instance, a dynamic IList<T>. It isn't completely
clear how to find the domain of the function without stepping through
through all the valid indexes in the domain; for instance, we could
presume it starts at [0] where [0] != null and ends at [0...i-1] where
[i] == null. I still need to interrogate the library further to find out
where Scope/Generator figures out that it has a list on its hand instead
of an object; or, whether this only occurs with the employ of helpers
such as {{#each}}{{/each}}. In any event, that might be where to
interrogate the Dynamic.InvokeGetIndex(instance, { index }). For now,
I've tested this to work with a specialized System.Dynamic.DynamicObject
class, which does override the TryGetMember() method, and Mustache# does
in fact invoke this method, thanks to Dynamitey.
