More work on FontAwesome 5 support

* Removed redundant escapes from isMobile regex and some others.
* Added fa-heading class to heading icon so it works on FA5.
* Changed fa-picture-o to fa-image so it works on FA5.
* Added noDisable flag for icons that is then handled in the createIcon function.
* Changed 'http://' default for links to 'https://'.
* Added noDisable to guide icon.
* Removed opacity change on toolbar hover (was 0.6).
* Removed opacity default (was 0.8).
* Removed default icon color (was #2c3e50).
* Added opacity change to disabled buttons, they get opacity of 0.6 when disabled.
* Added Node 8 and Node 9 support.
* Removed Node 0.12 and Node 5 support.
