Update to ilib build 20140719-build-7.0-001

* Added support for the Persian astronomical and Persian algorithmic calendars
    * The Persian algorithmic calendar is named "persian" and the algorithmic one is "persian-algo".
    * Switched Iran and Afghanistan to use the new persian astronomical calendar by default.
    * Fixed the date range formats for gregorian in Iran.
* Added "calendar" option to the date formatter factory method in addition to "type". The two mean the same thing.

Bug Fixes:

* Fixed completely broken Thai date formatting unit tests, and then fixed the code to pass those tests properly. Thai solar calendar works properly now.

* Fixed up date formats for Kurdish, Hebrew, Pashto, and Urdu to appear correct in right-to-left (RTL) contexts. This was done by adding the Unicode LTR character in front of strings that start with numbers so that the numbers would appear correctly in a LTR fashion when embedded in an HTML tag that is RTL.
