Tack - 0.1.0 release

[SeanTAllen]

We want to release 0.3.0 once we have merged #95 and #91.

This is my thought on approach. Let's do:

• release related portions of rename first in particular, dockerfiles etc. (including renaming this repo)

by doing this we won't break existing stable usage and have a weird "if i use master if is one thing, if i use release it is another". that would be a pain to deal with.

• merge replace usage of options with cli #95

• update Rename pony-stable to tack #91 to make additional changes related to replace usage of options with cli #95

• merge Rename pony-stable to tack #91

@ponylang/core can I get your input on the plan outlined in this issue? If you are good with the general approach, I can start to flesh out the plan.

Go ahead! I can do the #91 updating after #95 is merged, if you like @SeanTAllen

@mfelsche i'll handle it.
