Upon popular demand (#788), we are starting to use semantic versioning in tview. A lot has happened in this repo already so it didn't seem right to start with v0.1.0. A few notes about this decision:

• Not every commit will get a new version. Only when I feel that there have not been recent reports of major bugs, I will increase the version and create a new release.
• This is thus based on the assumption that recent, untagged versions will be used by the community and issues will be reported. Please do both.
• Consequently, as with any project, a release is not a guarantee that it is bug-free.
• As the "v0" prefix indicates, we are still in the "alpha" phase. This does not mean that I plan on breaking things. Please refer to the repo's main README for details. However, at this point, I am not completely sure that it will be necessary to introduce a breaking change so it'll remain at "v0" for the time being. (Maybe it will remain there forever. You never know.)
