Add the snippets to the completion box when the character at the left of the text cursor is a delimiter.

Done-with: Christian Kamm

Activate the global completion when the the character at the left of the text cursor is a delimiter.

Yet another quick and dirty hack while waiting for the real binding pass.

Activate the function-like completion only when the character at the left of the text cursor is a `('.

Just a temporary hack to get completion for user-defined components. It should go away as soon as we have a decent binding pass.

There can only be one root element in an XML document, and when we try
to read another one we get a premature end of document error.

The automatic activation of snippets can be rather unexpected. Also
provided some ad-hoc icons for snippets and QML completion items.

Changed the QML/JS editor to treat .qs/.js files as JavaScript, and invoke the appropriate parser for it.
