Do not use libcurl for reading local files

Browse source 
We originally used libcurl for both downloading images from
Internet and reading local files to have the same code path for both.

It doesn't work that well in practice, as Qt and libcurl are not
on the same page how special characters such as Chinese characters
are represented in a local file URL.

So create a new class to handle local files.

Closes #76
