Implement backup functionality for gtk.css

[needlesslygrim]

Instead of just overwriting gtk.css with a new gtk.css when applying the theme, we write the current contents of gtk.css to gtk.css.bak then write apply our changes to gtk.css

I'm trying to implement the restore functionality now, it's taking a bit longer than expected.

[needlesslygrim]

If you check main.py, you will see how far I have gotten. It hasn't been fully done, because I am getting the following error when trying to click the restore button. I tried moving the method from where it originially was, above the reset_color_scheme method to above the show_restore_color_scheme_dialog method but still no luck.

Traceback (most recent call last): File "/app/lib/python3.9/site-packages/gradience/main.py", line 445, in show_restore_color_scheme_dialog dialog.connect("response", self.restore_color_scheme)

Could you show the full traceback?

Currently, the management of presets is very basic. Having the ability to restore, backup would be great 👍.

Also for the style, please use 4spaces or 1 tab (there is a lot of style change in your PR

Also, I suggest to join the matrix room or the discord server (they are bridged)

Oops

[needlesslygrim]

I still haven't been able to get that code to work. Am I missing some weird thing in GTK?

Same error ?

[needlesslygrim]

Same error ?

yea, and I can't get it to build again

This formatting across whole main.py is very confusing, as it's hard to even see what changes you've added. You should start again with a clean file, put changes related to PR in it, and maybe add formatting in another commit.

Yup, I kept on getting inconsistent uses of spaces and tabs for indentation errors since I was stupidly trying to do actual development work with builder so I converted the whole file to tabs using Pycharm. I'll take the methods out and put them back in then push again.
