Improve tooltip tringgering,make it configurable...

Improve tooltip tringgering,make it configurable As until now, when pressing tab and a white space was preceding the cursor The completion was triggerd with the whole namespace in it. Now if a whitespace or an opening bracket is just befor the cursor it will try to display a tooltip. The logic to find what object_info_request is send have been sightly changed to try to match the expression just before the last unmached openig bracket before the cursor (without considering what is after the cursor). example (_|_ represent the cursor): >>> his_|_<tab> # completion >>> hist(_|_<tab> # tooltip on hist >>> hist(rand(20),bins=range(_|_ <tab> #tooltip on range >>> hist(rand(20),bins=range(10), _|_ <tab> # tooltip on hist (whitespace before cursor) >>> hist(rand(20),bins=range(10),_|_ <tab> # completion as we dont care of what is after the cursor: >>> hist(rand(5000), bins=50, _|_orientaion='horizontal') # and tab, equivalent to >>> hist(rand(5000), bins=50, _|_<tab> # onte the space again >>> hist(_|_rand(5000), bins=50, orientaion='horizontal') # and tab, equivalent to >>> hist(_|_ the 4 give tooltip on hist note that you can get tooltip on things that aren't function by appending a '(' like >>> matplotlib(<tab> Which is kinda weird... so we might want to bound another shortcut for tooltip, but which matches without bracket... additionnaly I have added a "Config" pannel in the left pannel with a checkbox bind to wether or not activate this functionnality Note, (rebase and edited commit, might not work perfetly xwithout the following ones)
