Renaming SOT325 footprint to SOT353, adding SC88A footprint.

The current SOT325 footprint (as included in pcb 20100929) gives a wrong footprint w.r.t. pin orientation:

1 |  | 5
  |  | 4
2 |  | 3

this should have been:

1 |  | 5
2 |  |
3 |  | 4

Furthermore, googling for "SOT325" gives:

1) footprints in gedasymbols.org created by DJ.
2) according to www.nxp.com SOT-325-1 is a SDIP20 package (300 mil DIP).

IMO SOT325 should be renamed to SOT-353-1 --> SOT353, or SC-88A (JEITA standard) -->SC88A, or MO-203 (JEDEC standard).
The latter is not a regular name designation in pcb (yet).
All names to be converted without dashes, as not to frustrate M4.
