Profiling results in ASCII format: non-monospaced font is not optimal

[tinchodias]

The AndreasSystemProfiler class offers very convenient API in class-side to profile. The profiler results tree is printed with ASCII lines between sibling nodes, to help reading it. IMHO this is good, but monospaced font would help even more. As it happens with "ASCII art" in general.

This also happens in the "Full Report" tab of the Time Profiler GUI (and this is Pharo 13 but also in previous versions):

Steps to reproduce A

1. Evaluate AndreasSystemProfiler spyFor: 1
2. The result is presented in a window with sans-serif non monospaced font.

Steps to reproduce B

1. Click on World Menu -> Debug -> Start profiling all Processes
2. move the cursor to top, to conclude profiling and see the results in a nice GUI.
3. Click on the "Full Report" tab

Case A

Current... non-monospaced:

My idea... make it monospaced:

Case B

The "Full Report" tab of the Time Profiler GUI would benefit from monospaced font too:

For the case of AndreasSystemProfiler API, it is opened this way:

doReport
	"Report the results of this profiler run"
	UIManager default edit: self report label: 'Spy Results'

maybe monospaced font can be set here.

However, it would be great that doReport opens a variant of the 'Time profiler' GUI.

In other words, I see as an alternative to my original comment that after evaluation of AndreasSystemProfiler spyFor: 1, the user could inspect the results in something like the Time profiler but without the button bar and code editor panel on top:
