v0.7.3 - Credential fixes

Changes

• Fixes authentication w/ Tarmac to use rbx_cookie so that it also supports credentials on windows. (since Roblox changed this)

---

This may also have the side-effect of making the cookie not have to be specified on MacOS. I haven't tested this theory though, so lmk!

0.7.2 Beta

Changes since 0.7.1

• Using tarmac sync --target local with spritesheets now separates the spritesheets with suffixes, e.g. spritesheet-1, spritesheet-2
