CD_KICK (cash drawer code appears wrong). #10

Hi

I couldn't get the cash drawer opening when using a TM81.  Based on this 
documentation 
http://nicholas.piasecki.name/blog/wp-content/uploads/2009/12/ESC-POS-Command-Gu
ide.pdf  

a pulse duration is required which is not included in the current code.

The docs say ASCII DLE DC4 n m t 

This outputs a signal specified by t to the connector pin specified by m. 
 m = 0: #2 Pin of the drawer kick connector 
 m = 1: #5 Pin of the drawer kick connector 
 On time is set to t x 100 msec; Off time is set to t x 100 msec

The current code has 

CD_KICK_2 = '\x1b\x70\x00'     # Sends a pulse to pin 2 [] 
CD_KICK_5 = '\x1b\x70\x01'     # Sends a pulse to pin 5 [] 

Which didn't work.

I changed the constants to 

CD_KICK_2 = '\x1b\x70\x00\x50\x50'      
CD_KICK_5 = '\x1b\x70\x01\x50\x50'     

Which works reliably on the TM81
