Zend_Locale_Format does not format numbers properly

[gregsmirnov]

According to documentation Normalization and Localization

1. Zend_Locale_Format::getNumber should round the number when precision is specified and should truncate number when number format is specified.
2. Zend_Locale_Format::toNumber should be universal and format with standard and custom CDLR formatted number patterns. This method is used by Zend_Currency:toCurrency for money formatting.

Added tests that show that there are issues. gregsmirnov@71d9151
