Is there a way to disable those sticky edges (where the window resizes when it is moved into the edge of the screen) through command line/dconf editor?
If you mean by sticky edges that windows change their appearance when they are moved close to the edge of the screen (e.g. get maximised), you can indeed disable this in elementary freya 0.3.2. The path within dconf-editor would be:
org - pantheon - desktop - gala - behavior
There you can uncheck the box named edge-tiling.
