Refactor ion-vue-router

[michaeltintiuc]

Usage

There are no major changes to usage:

<ion-vue-router />

There are 2 properties that ion-vue-router accepts:

• name - the name of the view, which is passed to router-view as per VueRouter docs
• animated - disables animations, the value is passed to ion-router-outlet

<ion-vue-router name="myView" animated="false" />

Changes

• Refactor ion-vue-router into a functional component which yields a performance boost as per Vue docs.
• Improve ionic transitions between routes, this mainly fixes the issue of navigation while a transition is in progress.
• Update router interface
• Improve Promise error handling for ion-router-outlet transitions
• Remove transitionless router as in hind sight it is really unneeded
• Remove unnecessary router options
• Remove support for in-browser support as ionic itself does not support this
• Update rollup config as per this issue
