[Vimprobable-users] Add support for setting download path

[Lingnan D. <dln...@gm...>]

Hi, 

I'm using Arch Linux and every time a newer version of vimprobable2 comes
out I have to change the DOWNLOADS_PATH definition in config.h. I wonder
if this option can make into the :set command? That would be much more
convenient as I can then put that in my rc.

BTW, vimprobable2 1.3 doesn't seem to take care of that DOWNLOADS_PATH
definition. After changing it like I did for previous versions the
browser still keeps downloading files in my home directory. I wonder if
anyone else has had the same problem or it is just a problem on my own
setup.
