Initial work on macplatform implementation
Add more todos.
Make checking for clipboard change more efficient.

Don't actually capture the data and work with it,
just check the number of times the clipboard has
changed.
Fix inability to run in background on Mavericks.

Add MacActivity class for handling starting and
stopping of "activities" through NSProcessInfo.
This allows CopyQ to continue running in the
background on OS X 10.9.
update TODO list.
Add MacTimer to allow setting tolerance.

Mavericks has the ability to set a "tolerance"
on an NSTimer, which allows the OS to more
efficiently schedule timers. This adds a class
which allows CopyQ to make use of that.
Merge branch 'master' of https://github.com/hluk/CopyQ into mac-support
Complete some TODOs.
Add script to generate icon.icns.
Properly package the .app.

- add icon
- hide app in dock
- copy plugins into the app bundle
- updated TODOs
Fix packaging of copyq.app.

Add a new target on OS X to allow
"make copyq.app". This creates an app bundle
and copies the Qt framework files into it
properly. Also added explicit dependency on
QtSQL to ensure that it gets packaged in the app
bundle.
