The onlineDocs.py module.

These are just simple functions to automatically open the correct python version documentation from the official site. Once pyrrhic-re is fully refactored these functions can be placed in another module if wished. 
I thought about making the version variable global in the module since it is used by both open functions, but I want to hear about your opinions. Also I might make the string operations into list operations, but it won't get us any major performance gain. Especially if we make the version variable a global variable. This string operation is just more readable. The minor version is excluded, because the online docs do not use it for the documentation url.
Now I only need to know what "Python Regex Help" will be to add it.
