[astro] new application and server running smoothly

It looks like everything is up and running smoothly, so Nate can start 
up searches on milkyway if he wants.

To get the binary to create searches run (from fgdo/bin/)

make -f make.boinc_sched clean (to make sure none of the object files 
are for a different architecture)
then
make -f make.boinc_sched start

searches can be started as follows, for example:

sudo -u boinc ./milkyway_start_search -app milkyway -cwd 
/export/www/boinc/milkyway/results/milkyway -gen 500 -mw_stars 
stars-79.txt -mw_parameters parameters-79_random.txt -s nm_stripe79_r1

in this case, this uses the file stars-79.txt as the stars file for the 
search, parameters-79_random.txt for the astronomy parameters, and names 
the search nm_stripe79_r1

Currently, all search names must start with 'nm_' because this lets the 
server daemons know that the search is running the newton method.

Make sure that the integral size is at least:

convolve: 60
r[min,max,steps]: 16.000000, 22.500000, 700
mu[min,max,steps]: 311.000000, 416.000000, 1600
nu[min,max,steps]: -1.250000, 1.250000, 160

This makes a WU take around an hour which is pretty ideal for server 
load.  It would be nice if we could come up with some other ways
to make the WUs take longer without just increasing the number of 
steps.  Maybe we can talk about this at the meeting this week.
