bug ChanVariable for asterisk 11 and early

[romkazor]

Hello, in some early version of asterisk ChanVariable looks a little differently, and event parser show only last ChanVariable (only CDR(dst)=102). In later version of asterisk event parser show dict of ChanVariable. How can I fix this?

Asterisk 11 (bug)

Event: Hangup
...
ChanVariable(Local/101@from-internal-00000023;1): CDR(dcontext)=from-internal
ChanVariable(Local/101@from-internal-00000023;1): CDR(dst)=101
ChanVariable(Local/102@from-internal-00000023;2): CDR(dcontext)=from-internal
ChanVariable(Local/102@from-internal-00000023;2): CDR(dst)=102

Asterisk 12+ (ok)

Event: Hangup
...
ChanVariable: CDR(dcontext)=from-internal
ChanVariable: CDR(dst)=101
DestChanVariable: CDR(dcontext)=from-internal
DestChanVariable: CDR(dst)=102

I wrote ugly fix, but it works, in event.py after 39 string:

before:

try:
                (key, value) = lines[i].split(': ', 1)
                if key in Event.parsers:

after:

try:
                chanvaris = 'ChanVariable'
                if lines[i].find('Channel: ') != -1:
                    channel = lines[i].split(': ')[1]
                if lines[i].find('): ') != -1:
                    chanvar = lines[i].split('): ')[0].split('(')[1]
                    if chanvar != channel:
                        chanvaris = 'DestChanVariable'
                if chanvaris != 'DestChanVariable':
                    (key, value) = re.sub(r'\([^)]*\)\:', ':', lines[i]).split(': ', 1)
                else:
                    (key, value) = re.sub(r'ChanVariable\([^)]*\)\:', 'DestChanVariable:', lines[i]).split(': ', 1)
                if key in Event.parsers:

I will think about it and try to do something.
Probabily I will delay, I'm busy with the work, but as soon as possible I will work at this.
Thanks for the bug report and for the suggestion.
