[MediaReport]: New image DPI option

[Mattkmmr]

A possible solution to fix issue #11492. It requires #1007. A more detailed description can be found there.

I tried to test this from CLI on Windows and got the following, what am I doing wrong?
Failed to write report.
Traceback (most recent call last):
File "C:\Program Files\GrampsAIO64-5.1.4-prelim\gramps\cli\plug_init_.py", line 699, in cl_report
my_report = report_class(database, clr.option_class, User())
File "C:\Users\dave\AppData\Roaming\gramps\gramps51\plugins\MediaReport\media_report.py", line 64, in init
self.window = self.user.uistate.window
AttributeError: 'NoneType' object has no attribute 'window'
Cleaning up.

(my idea is to be able to generate reports from a script file)

@lordemannd The report does not work for CLI in the current state, because it's using dialog windows which require a GUI.

The report is coded as if can run in CLI mode (in the .gpr.py file), but the original author did not take that into account when he created the dialogs; he assumes that they will be run in GUI mode. The dialogs should be using some user type agnostic code, that would work equally well in GUI or CLI mode.

[lordemannd]

A little more testing:
CLI: MediaReport does respond to the show options command, so the CLI user can see how to enter options.
(not thoroughly tested)

Books: I added the Book report mode to media_report.gpr.py
report_modes = [REPORT_MODE_CLI, REPORT_MODE_GUI, REPORT_MODE_BKI],

By this 1 line change, the book report seems working and was able to produce a pdf with MediaReport for 3 separate images.

The dialogs in question occur after the initial options dialog; they occur during actual processing. So yes, it will appear to work unless you actually run the report.

@lordemannd I updated the report and it should no longer rely on the Gramps GUI window when in CLI. Please test if it is working now.

I have to fix more of my report and tool addons also using dialogs, since I only test in GUI mode and didn't thought enough about CLI related issues. I also didn't knew I forgot to add the REPORT_MODE_BKI to all of them, so people can also use them in books. 😅

@Mattkmmr, oops I guess I didn't see your change in Sep 2021, I will take a look now at your recent changes.

@Mattkmmr, sorry for the delay, I have left some notes on bug report 11492.
