SettingsWidgets: Put JDK path field to the first place
SettingsWidgets: Put JDK path field to the first place

JDK should come first, because Android SDK depends on it. If a
user fills the form from top to bottom while installing the tools,
[s]he will have problems with the Android JDK entry because of two
reasons:

1) In order to launch the Android SDK Manager (in order to install
   the platform tools) Java is required.
2) On Windows the Android SDK now comes with an installer (unlike
   the .zip file on Linux/OSX) which enforces the JDK to already
   be installed beforehand.
