[PD] purr data 2.1.1

Purr Data 2.1.1 is out. https://git.purrdata.net/jwilkes/purr-data-binaries/tree/master

I added a "dropdown" widget to the "Put" menu.  The interface isn't yet stable, but it should be usable if people want to play with it. Changes:

• normalized range for [bendin] (keep old behavior under legacy flag)
• added "mouseenter" and "mouseleave" events for data structures
• fixed "Recent Files" under Windows
• cleaned up documentation in repo
• fix for [midiclkin] (#255)
• added "l2ork_version" message for [pdinfo]
• make loader search order the same as Pd Vanilla
• fixed cord inspector font size
• silence spurious error when autopatching a signal object
• added a [dropdown] object for choosing a value for an atom box (interface not stable yet)
• made gatom resizable by click-dragging in edit mode
• added "<ctrl-mousewheel>" for zooming
• added solarized and inverted solarized gui presets
• fixed mycanvas stroke color updates
• improvements to mode 4 of intelligent patching
• fixed "<Delete>" not deleting a selected object on some systems
