Add some cmake files to the gitignore list
cmake: Add extra lib and include paths when building on MacOS

When compiling with cmake on MacOS, search for the SQLite library and
include files in some other irectories before falling back to the standard
paths.
Maybe this fixed the issue at
https://github.com/rp-/sqlitebrowser/issues/42
Update the about dialog

Fix the link to the Qt project page. Also link to their page for license
information instead of pointing at a non-existant file in our
repository. This fixed issue #5.

Mention the Silk icon set in the about dialog and link to its page. This
should also make the hard-to-find CREDITS file dispensable.

Generally redesign the about dialog to use layouts for its design.
make the aboutdialog a bit higher, didn't fully fit on my system
plot: add a button to save the current plot as different file formats
Added URL for the new project website

Doh!  Just realised it's not explicitly mentioned anywhere yet.
Trivial formatting tweak
Update Windows icon and add script for creating new icons in the future

Add a script that takes the PNG application icon and converts it into a
multi-res Windows icon file.

Update the Windows icon file to match the new application icon.
Plot: Suggest file formats in save dialog
Make sure the SQL editor has got the focus after creating a new tab

Focus the SQL editor of a newly created tab to make sure it receives
keyboard input without need to click it first. On my system this wasn't
the case after starting the application, i.e. the first time the SQL tab
is used.
Add .DS_Store to .gitignore

OSX adds .DS_Store files for housekeeping metadata.  No need to
store it in .git.
Add placeholder 256x256 OSX icon image.

I'll do a proper one with all of the recommended sizes later if
John still has the source .svg.
plot: no selection for tree plot columns widget
plot: axis color is now chosen on activating an Y axis
Convert README to Markdown

This lets us use exactly the same content for the README and the
GitHub Pages based website.
Add John T. Haller to history, various markup and other README tweaks
