ZF-10: Incorrect input filtering methods names

Description

There are incorrect filtering methods names in Zend_Filter_Manual. According to the library, the filtering methods now should be prefixed by "test" but now they are prefixed by "is".

For example instead of isAlpha() should be testAlpha().

Comments

I'm wondering how should be prefixed static methods in Zend_Filter class. In Zend_Filter_Input they are prefixed by "test" but in Zend_Filter class they are still prefixed by "is".

Changing fix version to 0.9.0.

This has been fixed.
