KMarquart edit handbook instructions branch name and spelling errors

Why is this change being made?

Editing Handbook Instructions on Step 12- Clarification on creating new branch name- cannot contain spaces as the branch will not create and will keep erring out on you on the WebIDE- it does not tell the user what is wrong with the branch name it will just keep popping up a dialog box to create a new branch request.

Also corrected spelling from intial to initial on the team page update fields.
