Add level references to BGA document (#1510)

Added "Learning Path" sections to the BGA conversion document with references to the approximate H-Group convention level they correspond to.

Add precise level references to the Advanced section.

+The above should take you up to parity with the Level 2 or Level 3 H-Group conventions. Note that _Bluffs_ are **turned off** at H-Group levels 10 and below in favor of _Layered Finesses_ (below). Go join a few pick-up games with us!

 ## Convention Changes (Intermediate)
 
 Ok, so you've made it this far. The changes so far probably sound pretty strange, but at least most of the core stuff is still the same. Before reading further, you'll probably want to play a few games with us to get a feel for how the basics work. Beyond the basics, there are some other changes, as well as some new moves.

 - By extension, it is also possible to perform a _Double Finesse_ where both promised cards are _Layered_ behind other playable cards. Essentially, this means that when playing with good players, you always have to keep in mind that a _Finesse_ could be _Layered_.
 - Why do this? It's pretty awesome and one of the most fun parts of playing Hanabi with our group.

+The above should take you approximately up to parity with Level 10 (the last level before _Bluffs_ are added). Make sure to review the convention documents, such as the _Allowable Stall Clues_ table, and try the quiz questions in the convention documentation. Then come play with us!

 ## Convention Changes (Advanced)
 
 These are conventions that we don't typically turn on for new players, but we do use regularly in high-level games.

+- In our group, we arbitrarily agree that any card used to initiate a _Bluff_ can be either a one-away card OR a 3.

 - Oftentimes, a player will have two or more playable cards in their hand and have a choice as to which one to play.
 - On BGA, it is typical for people to play the cards that lead into teammate's hands. However, you are ultimately allowed to play your cards in whatever order you want, and no-one really pays too much attention.

 ## A Concluding Note
 
 Reading the stuff on this page will give you the major tools that you will need to play with our group. You can and should stop reading now and play some games with us! There's certainly some other minor things to learn, but you will quickly learn the rest from direct experience and post-game reviews.
