Add option to clip tab names in editor

I don’t really need the full file’s name to know which one it is, exactly - an option to limit the number of characters would be helpful to have more tabs within a click’s reach. Examples:

1. Clipping to (e.g.) name_maxlen=7 (excluding ~.py)
2. If names cannot be uniquely resolved within name_maxlen, extend until a differing char is met

The full names can be kept in the clickable dropdown or Ctrl + Tab.

@dalthviz I agree on your named case, but as an “option” it can be turned off any time; I frequently work with long filenames I’ve opened dozens of times over, the few I haven’t I could hover over to see the full name anyway. Also, my original idea was to have the name “fade” instead of inserting a placeholder character - but latter seems easier to implement and does the trick anyway.

Btw, PyCharm has an option to hide file extensions, which’d also help; alternatively, “if not .py, then show” - but I’ve never had to work with non-.py in Spyder.

Maybe it could be useful if you consistently follow a convention like file, file_test, file_*_, although I think there are also cases where for example a user is just trying to explorer a code base he is not familiar with and seeing incomplete filenames could be troublesome.
