Align keywords and documentation with Python version

[Hi-Fi]

• generic documentation alignment (Inc. Check locators with colon)
• add missing keywords
• deprecate removed ones
• align element text contains -leywords to be case sensitive as in Python (Element Should (Not) Contain is case sensitive in Python but not in Java #75)

If I find differences between the Python version and the Java version with regards to the keywords, id it OK if I just create a new pullrequest per found keyword?

Sure, help would be very nice. Although one big thing e.g. with Open Browser is, that Java-version uses camelCase and Python snake_case, and changing that is a breaking change. When moving to Selenium 4 it's of course easy to make.

Cool, I'm currently running into the whole set focus thing. The python version is using Set Focus To Element and the Java version is still using the Focus keywork.
I'll fix this then. For each fix, I'll add a comment in the PR to tell you if it can wait or if an intermediate release is prefered.
The Set Focus can be faked by just using a Click Element most of the time so...
