MPIO 0.7.0

The MPIO Project provides support for using Digitalway/Adtec MPIO digital audio players (DMG, DMK, DME, etc.) under Linux. It provides the user with a Linux kernel module driver, a user space library, and at the moment, one tool to access the MPIO player.
Most MPIO models should be supported without or with little change to the source code. Reading and writing to the internal and external memory works. Directory support is available since release 0.7.0. Unsupported are still: very new models of FL100 (this is being worked on and should be supported soon) and rare models with 3 internal chips (this needs some large code remodelling).
Enhancements:
- configure.in: bumped version to 0.7.0
- today is "release day"!
