Query Runner Rewrite

[arb]

• [ ] Need some kind of view manager to keep track of new tabs opened and their results
• [ ] Need a mechanism to hide and show the status bar items, currently, they stay open and we have no handle to hide them again
• [ ] Switch to type script
• [ ] Add a connection creater wizard thing
• [ ] Remove proactive code and just be reactive like the SQL plugin is
• [ ] Use a constants file
• [ ] Side by side view rather than whole page
• [ ] Better result styling

Not doing this for now, at least -- Studio is (currently) the place for that.
