[Timing Performance] Show full path of saved annotated td / output

[Eileen]

• In the Timing-Tab of a TD, in the output field, the path of the saved annotated TD or the saved output is shown, after the user clicks one of the save-button.
  At the moment only the path of the folder is shown, not of the exact file.

• Also the shown path should wrap to the next line (not be scrollable).

• The name of a 'saved output' file should be similar to the 'annotated td' file. Atm it is kind of weird (some kind of JS Date bug).

Optional:
Both output-file and annotated-td-files are saved as JSON documents. It would be nice if they would be formatted (adding new lines and spaces)before saving them.
Not possible as json file is generated by electron-json-storage dependency

Will be solved with the next pull-request from me (closing it to not forget)
