Solidify usage with multiple views into a file

[FichteFoll]

None of the event listeners were tested with multiple views into the same file. Also, none of the ViewEventListeners implement applies_to_primary_view_only, which returns True by default.

This is low priority but at least it's documented now.

Just wondered why completions didn't work for Sublime Syntax when I found it was a secondary view. Adding applies_to_primary_view_only() fixes the issue and seems to works well so far.

class SyntaxDefCompletionsListener(sublime_plugin.ViewEventListener):

    @classmethod
    def applies_to_primary_view_only(cls):
        return False

Just adding the callback didn't work for:

• SyntaxTestHighlighterListener
• SyntaxDefRegexCaptureGroupHighlighter

But did work for:

• SettingsListener (c42fd54)
• ColorSchemeCompletionsListener (c42fd54)
• SyntaxDefCompletionsListener (fef2f7a)
