- Fix the Source URLs to use mirrors properly

- Updated to 1.9.3
* This is a bug fix release, which also improves the tests for
building on Java 8.
* Note that Java 8 and later no longer support indexed bean
properties on java.util.List, only on arrays like String[].
(BEANUTILS-492). This affects PropertyUtils.getPropertyType()
and PropertyUtils.getPropertyDescriptor(); their javadoc have
therefore been updated to reflect this change in the JDK.
* Changes in this version include:
- Fixed Bugs:
* BEANUTILS-477: Changed log level in FluentPropertyBeanIntrospector
* BEANUTILS-492: Fixed exception when setting indexed properties
on DynaBeans.
* BEANUTILS-470: Precision lost when converting BigDecimal.
* BEANUTILS-465: Indexed List Setters fixed.
- Changes:
* BEANUTILS-433: Update dependency from JUnit 3.8.1 to 4.12.
* BEANUTILS-469: Update commons-logging from 1.1.1 to 1.2.
* BEANUTILS-474: FluentPropertyBeanIntrospector does not use the
same naming algorithm as DefaultBeanIntrospector.
* BEANUTILS-490: Update Java requirement from Java 5 to 6.
* BEANUTILS-482: Update commons-collections from 3.2.1 to 3.2.2
(CVE-2015-4852).
* BEANUTILS-490: Update java requirement to Java 6.
* BEANUTILS-492: IndexedPropertyDescriptor tests now pass on Java 8.
* BEANUTILS-495: DateConverterTestBase fails on M/d/yy in Java 9.
* BEANUTILS-496: testGetDescriptorInvalidBoolean fails on Java 9.
