Yet another file download script - for files from the Github repo browser
Prompts the user for URL, downloads the remote resource, prompts for filename and saves to a file.
If the clipboard contains a HTTP(S) or FTP(S) URL, the URL input dialog is
pre-filled with it.
The suggested local filename is extracted from the URL, if possible.
If a github file viewer URL is given, it is transformed into the matching
raw file access URL, which makes it easier to download files on github you
are viewing in your browser. Just copy the URL to the clipboard, change to
Pythonista and run this script.
if the downloaded file was a text file, open it in the Pythonista editor.
Until now, many things have been tried.
At last, '.pyui' file was able to be downloaded and performed.
