Project modernization for Xcode 4.2 and OSX Lion

Performed code modernization
Solved some of the deprecated warnings (those on NSSavePanel)
Tweaked the main.xib of MacFUSION.app in order to better manage the column widths, so that the mount/edit buttons are no more partially hidden on launch
Solved deprecated use of launchedApplications

Edited code in MFSettingsController#setup and mfcKaboomMacfusion() to replace launchedApplications with runningApplications, which returns an NSArray of  NSRunningApplication instead of an NSArray of Dictionaries
Corrected typo (missing "!" on mfcKaboomMacfusion()
changed, settings to compile in 10.7.4
added, sshfs build for 10.7 and 10.8
added, support for sshfs-static-lions binary
added, README for a frontpage in github
fixed, broken link in README
Added, toggle functionality on the MenuItem for the favories
updated credits.rtf
Cleaned up random bits of code
Added, images for filesystem states red for unmounted green for mounted
Updated, various resources and version strings moved to 2.0.5-dev
Fixed, issue where deleting a file system would fail and freeze the application.
    The problem was caused by the context pointer that NSAlert uses to send
    data on callbacks. It is not reliable to send an object as there is no
    guarantee the object will continue to exist on the callback. So a property
    was implemented. See the following discussion:
