General:

• Fix tsc-win commands in all packages ( / to // )
• Add build.angular.win in all packages ( / to // again )
• There is still an issue building and running everything unless a reference to @nativescript-community/ui-material-core package.json.

Demo-ng

• update demo-angular to ns8
• fix tabs xml so it shows up
• Change tabs to use one font based image source

Fixes:

#274 font based images now change color when selected ( resource based images do not )
#282 Color change triggered when Tab selected.

I noticed two remaining issues.

1. Non font based images don't change color when selected in IOS
2. The line under the tab which shows which tab is selected doesn't honor the highlight-color CSS not sure if that is intended or not.

@jcassidyav pretty awesome! First thank you for updating the angular demo...
Now i think it is all i need to test it.
about your question of non fonticons images color. Did you use iosIconRenderingMode ? have you tried with alwaysTemplate?

[jcassidyav]

@jcassidyav I thought that might be it but the code seems to select alwaysTemplate whenever there is a selected/unselected color specified so I'm thinking it is something else.

@jcassidyav that s why i want you to try and force it with alwaysTemplate

[jcassidyav]

Maybe I am misunderstanding, but I set iosIconRenderingMode="alwaysTemplate" on the MDTabStrip and set the code in getIcon to always set rendermode to 2 and I'm still seeing the icon not change color.

@jcassidyav ok then it does not work. Will have to try it. Thanks

I don't think the change here has degraded / caused the issue with the images not changing color, would it be possible to just look at this pull request without regard to the images icon issue?
