Add expanded git documentation to Canvas and Dev Guide

I have added the additional instructions for modifying the editor for Git Bash.

As there are no other requested edits, closing ticket.

For rebasing or squashing, the editor for Git Bash can be changed to any editor of the user's preference:
For instance to change the editor to notepad, vim or nano, use

git config --global core.editor "nano"
#or
git config --global core.editor "vim"
#or
git config --global core.editor "notepad"

# to verify the change, use
git config --global core.editor

To change the editor to any other, add the .exe path,

# Notepad++
git config --global core.editor "'C:\Program Files\Notepad++\notepad++.exe' -multiInst -notabbar -nosession -noPlugin"
#or Sublime Text 
git config --global core.editor "'C:\Program Files\Sublime Text\sublime_text.exe' -multiInst -notabbar -nosession -noPlugin"

I have created two new sub-pages in the IGB Developer's Guide under Developing Integrated Genome Browser.

• Git for Windows - this page includes information for downloading and installing Git onto a Windows machine.
• Git cheat sheet - this page includes useful git commands that the IGB team frequently uses.

I have also added a link to the Canvas Course pointing Windows users to the Git for Windows page.

To test: Please read through the various pages mentioned above and make sure that the text is accurate and clear.

Question for Windows users: Is there a way to specify a different editor after installing Git Bash?
-> Can someone try changing the default editor on Windows following these instructions?
