Fixed everything except conda and venv support

[kiwi0fruit]

fixes issues:

• Linux international desktop location #15
• Remove setters getters and insert Attributes docstrings #16
• Ability to be able to create a shortcut for a python "entry_point" #14
• Use custom name for shortcut #13
• Ability to log errors to a file object #12
• Ability to ignore errors #11
• Create shortcuts to files which dont exist #10
• Create shortcuts to directories #9

Suits my use-case of creating shortcuts in setup.py to executable entry_point and to dirs in site-packages (which also do not exist when code in setup.py is run).

@martinohanlon new PR.

[martinohanlon]

I am not going to merge this PR. As discussed in the issues there are significant differences between how I intend to deliver the API. I will work on the issues and progress.

Feel free to fork to the repo and use for your requirements but please maintain the license. Thanks a lot for your contribution, this will be a big help in me implementing the changes.

@martinohanlon please tell me if you are interested in shortcuts that activate environments. If yes - I will let you know when they are ready.
