message: Add more useful import example
diff: Managing script tags in component XML files can be tedius and time consuming. BrighterScript provides the `import` statement, which can be added to the top of your `.bs` files. Any xml file that includes that `.bs` file will automatically have all of its imports added as `<script` includes.
  ## Basic example
  +**src/components/Widget.bs**
  ```BrighterScript
  -import "lib.bs"
  -function DoSomething()
  +import "pkg:/source/lib.bs"
  +
  +function Init()
  SomeFunctionFromLib()
  end function
  ```
  +
  +transpiles to
  +**pkg:/components/Widget.brs**
  +```BrightScript
  +'import "pkg:/source/lib.bs"
  +
  +function Init()
  + SomeFunctionFromLib()
  +end function
  +```
  +
  +**pkg:/components/Widget.xml**
  +```xml
  +<?xml version="1.0" encoding="utf-8" ?>
  +<component name="BaseScene" extends="Scene">
  + <children>
  + <Rectangle id="myRectangle" color="#FF0000" width="1920" height="1080" opacity=".6" translation="[0,0]" />
  + </children>
  + <script uri="Widget.brs" />
  + <script uri="pkg:/source/lib.brs" />
  +</component>
  +```
