[Feature Request] Basic script generation

[isaacabraham]

Ionide + Paket has potentially a very nice story for scripting thanks in part to Paket's script generation feature. However, this isn't surfaced especially well in Ionide (indeed, many people don't even know about it). I would like to see a "all-in-one" script generation feature that would:

1. Prompt for a specific TFM (filtered by what's in dependencies file if possible)
2. Prompt for a specific group (if more than one in dependencies file)
3. Call generate-package-references in Paket to create reference scripts
4. Create an .fsx file which is pre-populated with a single line in it to #load the created reference script e.g. main.group.fsx
5. Open the script.
