updated build scripts for macOS and Linus and fix for mainframe.cpp

[wschadow]

This updates the build scripts with some more options:

Usage: ./BuildLinux.sh [-h][-u][-w][-g][-b][-r][-d][-s][-l][-t][-i]
-h: this message
-u: only update dependency packets (optional and need sudo)
-w: wipe build directories before building
-g: force gtk2 build
-b: build in debug mode
-r: clean dependencies
-d: build deps
-s: build SuperSlicer
-l: update language .pot file
-t: build tests (in combination with -s)
-i: generate .tgz and appimage (optional)

For a first use, you want to 'sudo ./BuildLinux.sh -u'
and then './BuildLinux.sh -dsi'

It also provides a fix for mainframe.cpp:

Exception Handling: Changed catch (std::exception e) to catch (const std::exception& e) for proper exception handling. Bracing and Indentation: Ensured all case blocks and conditional sections have consistent indentation and bracing. Closing Preprocessor Directives: Ensured that the #endif directive correctly closes the conditional compilation block

only the last three commits from today are relevant for this request

[supermerill]

I don't advise to use the nightly_dev to submit a pull request, as I use this branch for dev, and so it can jump averywhere at anytime. Please use instead master, master_dev, master_25, master_27. These ones don't move that much.

I guess I can just cherry pick your commits

to recreate this pull request?
