Separate tabs on the research screen for percentage vs. queue allocation

**What do you want to see?**
Split the research screen into two tabs: one for percentage allocation, and the other for queue allocation. Always show the allocated points for both systems, but only show the details for one at a time, and explain that you can use whichever system you prefer, or both if you want.

**How would it help players?**
Reduce confusion about how the research system works (Bearclaw said he found it confusing).

**Alternatives**
Have a mod option to disable one or the other system if it won't be useful
