ZF-5709: File extension to MIME type database
We should have the database of MIME types with relation to file extensions in Zend_MIME for use of various modules such as file transfer services, etc. It seems to be the most logical place to put such thing to.
This can be further extended by having finfo (file magic) interface which will guess file MIME not only but extension but also content. finfo is in standard PHP starting 5.3 but in PECL before that.
