R20Converter 0.4

Hey everyone!

I've been working hard lately on R20Converter, trying to finally add the support for actor conversions! I was tired of telling people "it converts everything for you.. apart from actors".

To say that it was tedious would be an understatement, but now it's done, so feel free to use the updated R20Converter and see if there's anything still missing or not being converted to your liking. If you've done a conversion before, unfortunately, you can't just replace the actors.db file (because the entity IDs would be different). 

One change that I did was port the converter to use Python 3 which makes it work much better with unicode (international characters) so for those of you doing non-english campaigns, that should make things slightly better.  I also fixed some issues I had with fonts, and fixed some inconsistencies when it came to the token's bar values.

Other than the big feature of having character sheets and NPCs finally converted, I've also added a new --add-walls-around-map option which should prove useful to those who don't want the side table in FVTT to be seen by players.  I've also added the option to do the conversion directly from a campaign.json file, so for those who have huge campaigns (like someone reported to me having an 11 GB campaign), you can now just export the campaign.json instead of the zip file and do the conversion on the json file.

Finally, I've updated the README file and made a tutorial video to make it easier for people to understand how to do a conversion, as I've found that many new users are lost with the concept of using the console. Rest assured though, I've decided to create a Graphical User Interface for a future version which should make it easier to use, especially as I'll make all of the command line options more visible.

If you find any bugs, issues, or have a feature to suggest, you can now do so on the github repository I created for the project.

Thanks again to all of you who have been supporting me and I hope this update is to your satisfaction (if not, let me know)!
