SI13: Set alpha value to a safer default of 0 instead of 10
alpha=0 (the new value) doesn't reduce MS transmission power during GPRS
as much as we did with alpha=10. This is to optimize for coverage and
to keep GPRS working at all cost, and not care about MS battery life
time or uplink interference in surrounding cells.
FIXME: This should be made configurable via the VTY and the normal
default (unless configured otherwise by vty/config file) should be '6'.
