p_load_gh vs. p_load_current_gh

[Dasonk]

I basically wasn't dealing with pacman stuff when the github functionality was added. I'm back now and looking over some of the code. The design choice in making two functions p_load_gh and p_load_current_gh seems odd to me. Typically we would set a parameter in the p_load_gh to indicate if we want the current most version from github instead of having a separate function.

Is there a reason for this choice? Should we change it or leave it as it is?

Side note: At some point I think we should map out how we want things to work. Originally we just had the initial aim to be installing/loading from CRAN but we've obviously expanded that scope. I think we should have a discussion about what we want our code to do in various situations when dealing with repositories other than CRAN.
