add precompiled header.
add QMAKE_PROJECT_NAME = libtiled
Fixed smooth rendering condition in Save As Image dialog

Now it matches with the logic used by Tiled in the map view, which is
what you would expect.
Fixed tile object outlines drawn at the wrong location

Closes #474
Allow to resize the animation timeline

This moves the frame list and tileset view into a splitter.

Fixes #716
Added a preview to the tile animation editor

Helpful when editing animations while you can't see them animated in the
map view.
Updated translation files

This is the string freeze for Tiled 0.10. It is a rather big update:

"Found 664 source text(s) (205 new and 459 already existing)"
Fixed crash when capturing terrain outside of the map

Fixes #726.
Removed commented code
Updated the Dutch translation and fixed a few source strings

The layer data format and rendering order options only apply to tile
layers, which is now more clear.
Removed MapWriter::setLayerDataFormat/layerDataFormat

Now it just uses the layer data format set on the map, which simplifies
things a little.
