Clipboard suggestions

[codokie]

I made the primary clipboard appear in the suggestion strip view as a suggested word whenever neutral suggestions are to be shown like in a beginning of sentence (fixes #167). Here is an example of the feature:

In android 7.0+, the API allows detection of sensitive clipboard content, and when that happens the content is redacted like this:

Suggestions will disappear if they are picked or 3 minutes have passed. There is also new setting in Suggestions settings that allows to toggle the suggestions. There will be a suggestion for number input fields only if the clipboard content is a number.

P.S. You can long press the clipboard suggestion and then press the X icon to dismiss it
