Update documentation

[HarelM]

Hi,

Can you please update documentation?
The following is incorrect:
var site = await WikiSite.CreateAsync(wikiClient, "https://test2.wikipedia.org/w/api.php");
Should be (I hope)
var site = await Site.CreateAsync(wikiClient, "https://test2.wikipedia.org/w/api.php");

Also would be helpful to provide more example of API usage, for example, I want to use this library to upload images, but I'm not sure how to do it from the documentation.

Ooooops. It's my fault…… There are some renaming involved in v0.6-int pre-releases. Since then I have paused the development process for a while and didn't have enough time to update README to reflect all of these changes. While actually I suggest you to try the latest pre-release, the current example given on README is a a mixture of v0.5 and v0.6. Still, if you continue to use v0.5, here is a documentation for that version.

I begin to realize it's important to update the documentation to reflect the changes on the class names from v0.5 to v0.6-int; thus I will close this issue when the documentation has been properly updated.

No Problem, Thanks for the quick response!
I really don't want to write yet another wiki client and other C# libraries seems extremely outdated, do If you don't mind I'll open up issues here to let you know what issues I find when trying to use this client.

Oh, that would be really, really helpful! I will make use of my intermittent time windows to handle these. After all, it's a v0.x library :-P

Updated README in 5c9eaa5. Now it reflects the changes of class names.
