Automatically evaluate NSs on save

[esuomi]

Hi!

This is tangentially related to a few recent issues, namely #70 and #59 - I'd like to get automatic evaluation of all code in project source files mainly to enable IntelliSense navigation immediately in the following two cases:

• When I open VSCode
• Whenever file is saved, either automatically due to focus loss or by hand

The main idea here is to keep code navigation as up to date as possible and the nice side effect of course is that it becomes really easy to check whether what I've just written makes sense or not. I'm sure there's some alternate route I could take and create a two-command macro in VSCode itself but I'd rather have this as add-on feature so that I can also turn it off at times if I'm, for example, working on such a humongous project that VSCode would grind to halt if it was autoevaluated.

(and with my track record this already exists in some form, I just couldn't find it before posting... :))

The feature seems to be easy to implement. I'll try to add it to the next release.

Not holding my breath for this one anymore :)
