This commit implements ENYO-3654 and ENYO-3664.
- build.js: Added some logic to prevent targetSDK version to be set to "None". None is equivalent to no value, and no value should not make it in config.xml for this particular attribute (PhoneGap would deal with the issue).
- PhonegapUIRows.js: I changed the logic of the updateConfigurationValue control. Min SDK, max SDK and targetSDK are all linked. the rules is min <= target <= max. Corrected a minor bug that prevented the correction of a bad max/min SDK version by using the other control (resp min/max)
- PhonegapUiData: added new SDK API version 19
Merge remote-tracking branch 'origin/master' into ENYO-3622
This supports JIRA ENYO-3643
The default value for phonegap version has been changed to 3.1.0.
The value 3.0.0 has been removed as it is no longer officially supported (see [PhoneGap build documentation](http://docs.build.phonegap.com/en_US/3.1.0/configuring_preferences.md.html#Preferences "phonegap doc")
ENYO-3576: Check if the Phonegap Build service is activated in order to update the content of the project attribute "downloadStatus".
