Visual Studio project and item templates

[SubPointSupport]

Moved from SubPointSolutions/spmeta2#163

M2 should have a better Visual Studio integration to reduce time waste on bootstrapping projects.

Must have features:

• project templates
• item templates

Would be nice to have features:

• console trace integration ??
• T4 templates ??
• Adding T4/PS templates for JS vars generation ??
• Adding SPMeta2 model debugger visualizer ??
