Better use for status bar

### What
Bring info currently behind “(i)” icon (characters and words counters, dates) to the status bar.

### Why
It's easier to check these info if they are always on the screen. Plus, it's an icon less on the top bar.

If there's space available, all info currently behind “(i)” icon appear on status bar. If not, a little “(i)” icon appears and show them when clicked.

### How

Start by locating the macOS note editor's status bar and the “(i)” info control that currently displays character, word, and date information. Check how the available space is determined and how the existing information view is shown. Done means the information is visible in the status bar when space permits, with an “(i)” control retained when it does not.
