Complete rewrite of the puller (fixes #638, fixes #715, fixes #701)

Temporary revert to the old debounce behavior. It's a bit bad and drives
up CPU usage, but mostly shows correct info in the GUI. This will be
improved shortly.

This reverts commit 5144330807, reversing
changes made to c34f3defe1.

+Building Syncthing from source is easy, and there's a

 Signed Releases
 ---------------
 
 As of v0.7.0 and onwards, git tags and release binaries are GPG signed with
-the key BCE524C7 (http://nym.se/gpg.txt). The signature is included in the
+the key BCE524C7 (http://nym.se/gpg.txt). For release binaries, MD5 and
-normal release bundle as `syncthing.asc` or `syncthing.exe.asc`.
+SHA1 checksums are calculated and signed, available in the
