Version 3 epic

[NikolayRys]

Features:

• [ ] Native share button https://github.com/NikolayRys/Likely/issues/156
• [x] In-text stylization(on @sashotoster)
• [x] Accessibility: https://github.com/NikolayRys/Likely/issues/161
• [ ] Document vertical alignment https://github.com/NikolayRys/Likely/issues/72
• [x] Remove counter separator https://github.com/NikolayRys/Likely/issues/125
• [x] Custom buttons support
• [x] Make clickable into buttons
• [ ] Add option to not appear until counters are fetched

Tech:

• [x] Remove likely() in favor of likely.initiate() (see #82 (comment)). And constructor.
• [x] Join .likely_visible and .likely_ready into a single class: it’s unclear why they are ever separate. (This could probably be a large breaking change because people can rely on one of these classes.) And remove the deprecation warning.
• [x] Bundle both JS and CSS into one file. This will let us get rid of Gulp and switch to Webpack completely.
• [x] Change interpretation of attributes: https://github.com/NikolayRys/Likely/issues/172
• [x] Add contributing guidelines https://github.com/NikolayRys/Likely/issues/17
• [x] SVG icon strings encode SVG paths but omit the M letter in the code. This causes issues when contributors submit PRs providing this button (e.g. #101)

Join .likely_visible and .likely_ready into a single class

I'd suggest adding a deprecation warning first, like "We're going to remove timeout option and ready modifier at all. Please, file an issue if you know a good reason not to" in v3.0 and see who's going to file an issue.

You are right, this actually might be a good reason to move some of the features into 2.5, let me think a bit which ones.

Note for self:

• review old branches if they contain anything worth considering\
• review dependencies
