Parse .Designer.cs file to detect renames

[tznind]

CodeToView is responsible for converting a users .Designer.cs code into a runtime state for the editor.

Currently the load process is as follows:

• Create a CSharpSyntaxTree from the .Designer.cs file
• Determine the view base class
• Create an empty shell .cs parse tree (i.e. to get InitializeComponent and constructor)
• Combine the two partials and compile into a new memory only assembly
• Mount an instance in the editor
• Apply runtime changes (making things visible, converting Data properties from string to Design etc (see CreateSubControlDesigns)

If a user renames fields manually then the Data property will not match the field name (see #211)

It should however be possible to use the CSharpSyntaxTree to find such assignments where the private field name does not match and either warn or override and take the users new name.
