Here are the suggested edits

Hello,

Here are the suggested edits.
Hope you like them.

Another small stuff, that I did not try yet but just thought of is to give the possibility to reference the syntax file from both:
new_view.set_syntax_file("Packages/Wiki/Wiki.tmLanguage")
and
new_view.set_syntax_file("Packages/SublimeWiki/Wiki.tmLanguage")
basically on a try catch if one fails to go to the other one.

Also if I'll figure how out maybe it would be nice to open the readme.md after install and to register the tutorial it in the menu and/or list the keyboard preferences.
