Bug 477962 - Create Basic QML Editor with Syntax Highlighting
Added a QML Editor which handles basic syntax highlighting for keywords, multi-line and single-line comments, and strings. The highlight colours are similar to that of Qt Creator and cannot be modified by users as of yet. Change-Id: Ied0ab0432a3a2a43f93733964747c792e29771c4 Signed-off-by: Matthew Bastien <mbastien@blackberry.com>
