Workflow improvements

[seece]

The addon could be easier to use with the following changes (see forum post):

• Angle and frame names are now determined automatically. Didn't make sense to expose those data for the user to tinker with.
• Each mesh to be rendered now has a new property, SpriteName, to determine file name output.
• Support for more than 26 frames; in such a case, only the first 3 letters of SpriteName will be used. The 4th letter will be substituted with a number that increases every 26 frames.
• Added property (set on the Empty parent) for mirrored sprite names, and single angle sprites.

These are already implemented in Nash's fork but it only works in Blender 2.79.

There are currently a few bugs with my fork, I've fixed some of them a few days ago, but this needs a little more testing... I don't recommend merging my fork in yet. :) I will post a new comment when I have thoroughly tested it and can confirm that it is 100% ready.

Thanks for the original script. I use it heavily for all my projects. :)

I'm glad to hear that script has proved useful. And don't worry about merging since this is just a feature wish list, not a plan to unify the forks.
