4 AltosUI and fixes some bugs in the AltOS firmware.

10 In TeleMini recovery mode (when booted with the outer two
11 debug pins connected together), the radio parameters are also
12 set back to defaults (434.550MHz, N0CALL, factory radio cal).
13 </p></li><li class="listitem"><p>
14 Add support for reflashing the SkyTraq GPS chips. This
15 requires special host-side code which currently only exists
17 </p></li><li class="listitem"><p>
18 Correct Kalman filter model error covariance matrix. The
19 values used previously assumed continuous measurements instead
20 of discrete measurements.

22 Fix some bugs in the USB driver for TeleMetrum and TeleDongle
23 that affected Windows users.
24 </p></li><li class="listitem"><p>
25 Adjusted the automatic gain control parameters that affect
26 receive performance for TeleDongle. Field tests indicate that this
27 may improve receive performance somewhat.

32 Handle missing GPS lock in 'Descent' tab. Previously, if the
33 GPS position of the pad was unknown, an exception would be
34 raised, breaking the Descent tab contents.
35 </p></li><li class="listitem"><p>
36 Improve the graph, adding tool-tips to show values near the
37 cursor and making the displayed set of values configurable,
38 adding all of the flight data as options while leaving the
39 default settings alone so that the graph starts by showing
40 height, speed and acceleration.
41 </p></li><li class="listitem"><p>
42 Make the initial position of the AltosUI top level window
43 configurable. Along with this change, the other windows will
44 pop up at 'sensible' places now, instead of on top of one
46 </p></li><li class="listitem"><p>
47 Add callsign to Monitor idle window and connecting
48 dialogs. This makes it clear which callsign is being used so
49 that the operator will be aware that it must match the flight
50 computer value or no communication will work.
51 </p></li><li class="listitem"><p>
52 When downloading flight data, display the block number so that
53 the user has some sense of progress. Unfortunately, we don't
54 know how many blocks will need to be downloaded, but at least
55 it isn't just sitting there doing nothing for a long time.
56 </p></li><li class="listitem"><p>
57 Add GPS data and a map to the graph window. This lets you see
58 a complete summary of the flight without needing to 'replay'
