How to handle Solicitations #67

I removed the line covering the urge not to create Code Solicitations.

My initial thoughts are:

1. A brief mentioning of DO NOT DO THIS in the contributing guide to cover folks contributing based on their opinion

From #40:

I agree with "no solicitation" in general, but this feels like either

1. a bit of a preemptive hard line to take or
2. something that should be spelled out explicitly in the code of conduct rather than in a document containing contributing instructions
