Allow MAPDRV.COM to read from INI file and map multiple partitions

[sdsnatcher73]

It would be nice if MAPDRV.COM could mount multiple partitions in 1 execution. Now I mount 5 partitions from AUTOEXEC.BAT it is a lot of back and forth between command processor and MAPDRV. If MAPDRV could have a parameter like /I MAPDRV.INI and then read from MAPDRV.INI the parameters of all partitions and mount them in 1 go it would save a lot of time.

MAPDRV.INI could have lines like
D: 2 1-1 0
E: 3 1-1 0
etc.
