fix installation script for Ubuntu 16.04, add script to install libembroidery-convert, adapt README

README.md

@@ -8,11 +8,15 @@ So I wrote one.
 
 Okay, not really.  I'm pretty terrible at GUIs, but I found this nifty inkscape extension that was created and hacked on by a couple of other folks.  It was pretty rudimentary, but it got the job done, and more importantly, it was super hackable.  I hacked the hell out of it, and at this point **inkscape-embroidery is a viable entry-level machine embroidery design tool**.

-Download the [extension's archive file](https://github.com/lexelby/inkscape-embroidery/archive/master.zip) and unpack the zip archive. Then, on a terminal, run the installation (and update) script from the archive's `bin` directory by first changing into that directory with `cd <path_to_the_archive>/inkscape-embroidery-master/bin` and then entering the command `sh install.sh`. The script will ask for your password to be able to install new software, remove any Inkscape snap packages that may be installed, and to update Inkscape to the current version. Restart Inkscape after the script has executed to see the changes take effect. You can also run the script again when you later want to update the extension (and Inkscape).

The script will ask for your password to be able to install new software, remove any Inkscape snap packages that may be installed, and to update Inkscape to the current version. Intermittently, it will require you to confirm a step by hitting Enter, or typing in 'y' or 'yes'. It will compile a library needed by wxpython, this will take some (a lot of, actually...) time. Restart Inkscape after the script has executed to see the changes take effect. You can also run the script again when you later want to update the extension (and Inkscape).
 
-Currently, the optional conversion program still needs to be installed manually, if desired.
+To also install the optional conversion program, run `sh install_libembroidery-convert.sh` in the same directory. This script will also ask your password in order to be able to install the necessary dependencies.
+
+Not tested with Ubuntu versions other than 16.04. If you try it out, please let us know how it went.

+Continue reading in the "Usage" section.
