MetaInfoFile should be a high-level interface

[GoogleCodeExporter]

The MetaInfoFile should be a hig-level interface for reading and writing
data. It functions as the base for both the JPEG and the TIFF classes.

It should provide the following methods:
- getExifTag(tag, record (optional))
- getIPTCTag(tag, record (optional))
- setExifTag(tag, payload, record (optional))
- setIPTCTag(tag, payload, record (optional))
- appendExifTag(tag, payload, record (optional))
- appendIPTCTag(tag, payload, record (optional))
- delExifTag(tag, record (optional))
- delIPTCTag(tag, record (optional))

In each case, the tag and record can be both a name or number. Record may
be omitted, although it might not be clear in which record a tag name
belongs. In that case an exception is raised.
The del....() methods should return False if the tag may not be deleted.

This is mostly fixed, except for a False return value with the del...() 
methods. This
is dependent on the provided tag tabels -> alpha2

v1-alpha2 is an intermediate release. This issue is shifted to v1-alpha3.
