modularizing BangleJS

Personal Reason
So you asked this I don't really understand why we're doing this, we could support the P8 with just another few IFDEFs.
So this isn't really about the P8 watch per say. This is actually about a different project in mind.

Project idea
I'm one of those weird people who loved the pebble watch, but the device is just so old it's hard to use now. So what i started looking into was how to replace the motherboard and what software should it run. Out of all open source watch "operating system" i found that yours seemed to make the most sense. Mostly because it allowed apps to be loaded from a web browser, which no other watch OS can do.

The problem is I'm planning on using hardware that is very different then what most people are using. I'm using a Nrf52480 and the memory LCD, but everything else is fairly different. So here comes the problem, i didn't want to pollute the main project with a lot of #ifdefs that were specific to my small project. So i was hoping I could break the code into modules then i could easily have my own repo with my own drivers that i could easily update down the line.

So that's where the P8 comes in. I thought trying to add the P8 into the code base would be a good test project to see how hard of a task it would be. Its also a watch i had lying around and stopped using it because it was very hard to develop apps for compared to the bangle watch.

As to why i didn't say all this stuff in the beginning. It mostly comes down to not knowing how serious i was about this project. This kind of project is a lot larger then any other project I've ever tried to do. So my thought was to see how hard it was to do the P8 watch and then see if i want to continue and try to make my own PCB for the pebble watch. My hope was either way i thought it could potentially help the project out.

So i hope this makes more sense and I'm sorry if i pressed to hard.
