Update dialog plug-in
Full paths on search clipboard are made relative to file chooser base
Use /usr/bin/tar instead of gnutar (which is removed on 10.9)

We were using gnutar to avoid the extended header keywords that bsdtar add to the archive (for non-ASCII file names) as those will cause older versions of gnutar (like the one included with 10.8 and earlier) to give warnings/errors when extracting the archive.

Issue #1180
Only show one warning per missing user when generating credits
Opt out of responsive scrolling

With responsive scrolling we need to return NO from isOpaque in order to get transparency and we cannot overload the scrollWheel: method (which we use to forward mouse events from the gutter to the text area).

I have also received a few crash reports that might be caused by responsive scrolling and one user has reported “sticky” scroll behavior.

So for now better just disable it, and see if it fixes all these issues.

Fixes #1135
Fix potential missing last line in encoding view

This would happen if last line was not newline terminated.

The fix does not take into consideration that last line might contain non-ASCII, in which case it should be highlighted.
Add gutter_styles_t::is_transparent
Do not set window as opaque when gutter background is transparent

Previously only the text view’s background would affect the window’s opaque property, which made it impossible to have a solid text view background with a transparent gutter.
