Auto-Completion

The VBIDE already automatically inserts parentheses and the closing `End Sub` / `End Function` / `End Property` token when you type a member signature and then move to another line (usually by pressing ENTER), and will also automatically close `"` double quotes in a string literal - and that's about the extent of autocompletion features in the VBE. With Rubberduck you can now type string literals and concatenate them more naturally. Opening a parenthesis automatically closes it and places the caret exactly where you need it to be; nested parentheses are matched, so deleting a `(` will also delete the matching `)` wherever it might be. These simple quality of-life enhancements might be subtle, but they make a huge difference in how it feels to _type code_ in the VBE.
