Glob Query Support and Removed gevent dependency from client

Hi

Changes in this patch :
1) I have added glob query support for taba names. 
2) Removed taba_client's dependency on gevent

Assumptions/Observations:

I guess even though the server and dao supports a list of names as an input parameter, from reading the request handler code, It looks like the user either gives a single Taba name or none at all. (This could possibly me extended to support comma separated list of names)
Currently, to check if the user has provided a glob, I just check if the taba name found in the request contains special characters "*?[]!". It is possible that if the name contains an escaped character, this check will break. (Maybe it would be good to specify that only alphanumeric taba names are allowed ??)
This is just an initial patch.. let me know if you need me to clean it up further or if im missing something
