added descriptions to TaintConfigSchema.json to explain its semantics

[StamesJames]

I started playing around with phasar a bit to look if I can use it on llvm code created by rust. At first I have used the analysis-config wrong so I wrote some descriptions into the schema. Maybe this can help future users too and I hope my descriptions are right.

Hi @StamesJames , thank you for your contribution. I have committed a minor change, making all the first letters of the description text capitals. Do you agree with that? If so, I'll merge.

[StamesJames]

Sounds good, thanks :-)
I also wrote some notes while playing around with PhASAR which almost are tutorials for using the basics of phasar-cli. I could contribute those too but if I understand it right I can't make a pullrequest for the wiki repo where your other tutorials are. should I just put them in an issue?

[MMory]

Would be good to have those tutorials, thank you! Yeah, an issue might be the best way.

Regarding this PR, the parentheses in line 22 break the build, I have not found an obvious way to escape them, maybe omitting them is the best way to go forward.

[StamesJames]

ah ok thanks for fixing this.
And I will write the tutorial and put in in an Issue :-)
