v4.5.1

What's Changed

• Keep filename and export button reachable next to the preview by @hefler in #28

Closes #27.

UI

• The filename field and the export/download button now sit in the same column as the code preview, pinned to the bottom of the window. A long preview no longer pushes the download button below the fold — no more scrolling past the whole output to get your file.
• The controls stay pinned whether or not the preview is showing, in both Design and Dev mode.
