Release of Version 4.5

The release of version 4.5

This gives us a new convenient way to write ejectives and implosives.
It also gives us more ways to use combining diacritics and the diacritics tab is a little bit better.

I think the diacritics tab and their use and explanations can be a little bit better.
The accompanying two scientific documents that I wrote have also been re-worded and revised.

I am not quite satisfied with the typable method, and it still needs to be updated to be able to
accommodate the combining diacritics better and it needs to reflect and conform to version 4.5
