Increases the falsing threshold when for the keyguard affordances

The minimum amount has been increased by 20dp and in addition the
Motion is cancelled whenever a POINTER_DOWN occurs, which should
help a lot with falsing.

Fix null handling in proxies.

ProxyInfo.getPacFileUrl() can not be null.  It will be equal to
Uri.EMPTY.  Checking for null was causing global proxies to never be
disabled.  Or more accurately, global proxies would be disabled, but
would reappear after a reboot.

ProxyInfo.getExclusionListByString() can be null.  If no
exclusion list was specified, the proxy settings would not be
successfully saved, they would disappear after reboot.
