Cache project names saved to lgtm

What's the Problem

As these scripts are used more and more by a researcher, there will be duplicate projects saved to lgtm.com. lgtm.com can properly handle duplicate projects (returning an error stating the project is already saved [I assume that's the case?]). This results in unnecessary HTTP requests which costs us time.

Potential Solution

Adding a local cache system that caches every project name that was saved to lgtm.com will allow us to reduce the number of HTTP requests sent to lgtm.com.

Issues With This Issue

I actually don't know how much of this will be a problem. I don't have enough experience working with these scripts. But at the most basic level, this makes some sense to me.

I'd just as soon not prematurely optimize. If it becomes a problem, we should absolutely fix it.

Sounds good.
