b1a43e57c7 Update device profile clockspeed. 
The Mega also runs as 16MHz so update device.clockspeed to match.

1f418098b2 Update device profile clockspeed & portdelay. 
Set clock speed to 16MHz.  Hopefully this value works fine with the
client since the previous 100MHz was not the actual clockspeed anyway.
Also, adjust the device.open.portdelay to 1500ms.  People can test
their own device for the fastest value, but this should be a safer
default for most people and hopefully eliminates som frustration for
first time users.

34aea7435d Update device profiles. 
Add the 'device.receive.timeout' values required by the latest
LogicSniffer client application.

f51d0bbb96 Improve pre-trigger sampling on below 500kHz sample rates. 
The sample loop was not padded properly in the loop waiting for the
trigger to fire. As a result it was sampling at a much higher rate than
the post trigger sample rate.  I've added some delays and padded it out
a bit, it needs further measurement, but is usable now.

3a6329775c Merge pull request #3 from scottp/master 
Correct long standing bug in the device profiles on github where the data was being reversed by the client due to the reverseOrder setting.  The sketch returns the data in the sampled order, but the client appears to expect it reversed, so the sense of the setting is backwards. Data is in the correct order based on a simple test program, even though the setting is "wrong".  Invert the comment as well.  Also increase the delay on the Mega as it doesn't always respond fast enough. Patches from scottp.

3c69ec10a1 ols.profile-*: Reverse IO order received in config 
Fixed reverseOrder and comments

As per this post:
http://dangerousprototypes.com/forum/viewtopic.php?f=57&t=2432

The comment talking about device.samples.reverseOrder is reversed. I have
fixed the order and the comment and tested.

7173e83e14 ols.profile-aglam.cfg: Increased delay time 
On testing a number of Arduino Mega boards, I found the device missing error.
Now it seems to be alwåays working if you set it to 2000.
