R20Exporter release

Hey everyone!

I think I'm done now with the R20Exporter tool. Sure, it can get some cosmetic improvements eventually, but it's mostly functional and stable, so it's time to release the tool publicly! Thank you all for being beta testers and helping me find all those bugs and edge cases!

I've set it up on github, and you can download it here. 

The main changes in this version is that it now also parses all the decks, rollable tables and the macros so they are available in the campaign.json file and the decks/tables' images are also downloaded and put into the zip.

Note that I've separated the R20Exporter and R20Converter into two separate projects, so their version numbers will eventually diverge and this means that R20Converter is not yet going to be publicly released, only the exporter. I need to finish support for actors and fog of war at least before I consider it done and I've been too distracted with all my other projects.

Right now, I'm working on adding drawing tools to Foundry VTT as a module, which hopefully will then help make the feature get merged into the core faster. I know that drawing tools and macros are the most requested features so I'm trying to help with that.

I do have a question for those who became patrons. I'm rather new to patreon and the concept of it, I don't know what most of you are looking for and if I could get answers (as comments or direct messages?) that would be great.

- Are you subscribed as a way of saying Thank you for work done in the past or to support future work?

- Are you subscribed because of Beyond20 itself, because of the work I'm doing on FVTT or something else entirely? 

- Are you subscribed because you want access to the patreon-only projects or you would have subscribed regardless?

I'm mostly trying to gauge my responsibilities in providing you with constant updates and/or with releasing the projects publicly and/or in making more of my work patreon-only. As I'm working on the new drawing tools module now, I'm struggling with the idea of making it patreon-only. I don't want to do that (I'm not used to releasing stuff that isn't open source from day one), but I don't know if patrons (you) would feel somehow offended if I don't give you exclusive stuff... so basically, I'm trying to figure out what people want!

Also note, starting next month, I'll be creating different patron tiers. I think I'll set access to the R20Converter tool as a 5$ tier level, and have a 1$ "Thank you" tier, if you have ideas/proposals for other tier levels, let me know! :) For those of you who are already patrons, you'd still get access to it, regardless of your contribution. If I can't override your tier with patreon's system, then we'll figure it out somehow or worst case scenario, poke me on Discord to get the latest version :) 

Either way, thanks for supporting me and I hope you're all happy with that decision :)
