* improved errorhandling a bit. At the initialscan we store
errors/warnings now in a list per partition and show the in the
partitioninfo dialog.
While executing an operation we collect all libparted exceptions in
a list and attach this list to the operationdetails when everything
is done.
* include/Partition.h,
src/Partition.cc: added 'Glib::ustring mountpoint'
* include/GParted_Core.h,
src/GParted_Core.cc: implemented set_mountpoints() to set mountpoint
in partitions.
* include/Dialog_Partition_Info.h,
src/Dialog_Partition_Info.cc: use Partition::mountpoint instead of
finding it ourselves.
