Add install section to README

[domWalters]

For now:

• Clone the repository to $HOME/.config.git-gui
• Change the shebang to #!/usr/bin/env tclsh
• Immediately after the shebang add source $::env(HOME)/.config/git-gui/style.tcl
• The style_during_apply_config needs to be called after this line.
• The style_during_window_load_state needs to be called after this line.

Ah, was already missing this.

What i did, was :

• copy the two proc definitions into git-gui.tcl
• call both at the locations mentioned

After that, starting git-gui produced errors, so:

• change two lines, commenting them out, i have:

      ########## PRODUCED ERROR ########### ttk::style element create Spinbox.uparrow from default
      ########## PRODUCED ERROR ########### ttk::style element create Spinbox.downarrow from default
  

After that, some parts of the interface where still quite bright, so:

• add two of the other suggestions:
  • "Official" Dark Mode for Git GUI prati0100/git-gui#64 (comment) (before last } of style_during_apply_config)
  • "Official" Dark Mode for Git GUI prati0100/git-gui#64 (comment) (before last } of style_during_load_window_state)

So, thought i'd share with you. Thanks for sharing what you did.

Nice, glad you got it working!

I did this on Arch Linux, so I imagine we may have had version differences.
