Default to apex_application.application_primary_language

Fixes #11
Also, correctly deploys v1.3.0 updates, oops

Bug fixes and enhancements w/IG

• Added apex.item().getPopupSelector for better IG integration.
• Better dialog position inside of modal windows (the dialog is now anchored to the calling window)
• Use p_param.value_set_by_controller to determine if regular item or controller. Now we can undo the hack

IG support!

Major features:

• #2 IG
• Floating Labels

This version is backward compatible with v1.0 and v1.1

However, it's worth noting that structurally, there's a big change. In v1.2 the plugin does not use a hidden item to store the JSON.  Instead, there's only one item element.  For the regular item, the initial data is specified in via a data-value attribute, but then maintained internally, for the IG, the data is set and retrieved by the IG via apex.item().setValue and apex.item().displayValueFor

Bug fixes

• Behavior change: Item languages can now be edited by default (the attribute "Edit Languages" is now set to "true" by default.)
• Bug fix: Issue when the initial creation of a record used a language code other than "en"
• For APEX 5.0.4 use v1.0.0 or get it from the test app f102_apex_504.sql

TEXTAREAS!

This plugin has now been in production use for more than 6 months. So it's time to call it v1.0.0 (about time!).
This new version also implements TEXTAREAS for multi-line editing.
This version is still compatible with APEX 5.0, however, next version may move to the new plugin architecture of APEX 5.1

Initial release

First release into the wild of the JTL (JSON Translation) APEX Item Plugin.
Although this is a pre-release version, the plugin code itself is almost ready for prime time with the missing feature of textarea fields.
