Upped PEAR Console_Table to 1.1.6

Hi, the PEAR Console Table 1.1.6 has been released.

It fixes the following PEAR bug:
Bug #20092      Table output inserts bogus \r character when not on Windows
https://pear.php.net/bugs/bug.php?id=20092
For the exact code changed see this commit:

https://github.com/pear/Console_Table/commit/332867db680716f8a60eb933deac6bfb1ae6b8f7

Once this new version of the PEAR library is in drush, drush users on OSX will
no longer have to ^Ms in the default drush table output.
