Option to hide "Loading profile" messages on start

Describe the problem: It would be nice to be able to hide the Loading profile/Loading module messages that occur when the shell starts up. I don't think this would make debugging issues with a module or profile more difficult, as if I put a wrong/gibberish command in e.g. my .murex_profile file, the file and line number of the offending command will still be visible in the stderr.

Possible ways to implement: Not sure, I actually looked into writing a pull request implementing this as config option in the shell app, with the default set to the existing behaviour of showing the messages. However, I ran into the issue that the messages are printed before the file is parsed. Setting the config option in .murex_preload would hide the later message about loading .murex_profile, but not the one about loading .murex_preload itself, etc.

It could well be that in practice this is unworkable or not worth the time, but if not I think it would be a nice feature to have.

Yeah, this couldn't be a setting in .murex_preload unfortunately for exactly the reason you outlined. But it could be an environmental variable and/or command line flag that is passed to murex upon start up. eg murex --quiet

Nice work on the PR @tiymat 👍
