[libextractor] LE 0.5.2 released (WAS: getting metadata from a buffer instead of a file?)

[Christian Grothoff]

Surprising myself, I just released libextractor 0.5.2 with support for getting
metadata from a buffer in memory (EXTRACTOR_getKeywords2).  This release also
adds support for exiv2 and of course fixes the compile error from 0.5.1.
