TextEditor.onDidChangeScrollTop is deprecated.

Hello,

> I get this message from Atom's Deprecation Cop

This is now a view method. Call TextEditorElement::onDidChangeScrollTop instead.
```
TextEditor.onDidChangeScrollTop (/usr/share/atom/resources/app.asar/src/text-editor.js:697:12)
color-marker.subscribeToMarker (/home/nico/.atom/packages/atom-color-highlight/lib/marker-mixin.coffee:66:49)
color-marker.init (/home/nico/.atom/packages/atom-color-highlight/lib/marker-element.coffee:29:12)
atom-color-highlight.createMarkerElement (/home/nico/.atom/packages/atom-color-highlight/lib/atom-color-highlight-element.coffee:307:15)
atom-color-highlight.markersUpdated (/home/nico/.atom/packages/atom-color-highlight/lib/atom-color-highlight-element.coffee:234:31)
(/home/nico/.atom/packages/atom-color-highlight/lib/atom-color-highlight-element.coffee:50:24)
```

弃用跟踪指向 marker-mixin.coffee 第 66 行，其中调用了 TextEditor.onDidChangeScrollTop。将其替换为 TextEditorElement::onDidChangeScrollTop。检查代码库中访问 editor element 的方式，更新调用，并在 Atom 中测试 package，以确保弃用警告消失。
