Create a tool to automatically download appropriate exported databases

[joxeankoret]

It's related to issue #9 : after multiple Open Source codebases have been exported and the web service for finding/download appropriate databases is created, create a new IDA plugin that "automagically" tries to find the appropriate libraries for the current target binary, downloads them and uses Pigaios to, at least, open a tab with the matches for each project.

The idea is to show the reverse engineer a series of potentially very-very good matches as soon as he/she starts the projects and let him/her import function names, function prototypes, structure definitions, enumerations, etc...
