Rename Character to Char to match upstream API naming.

This adds a breaking API change by renaming `SetCharacterCallback` to and `SetCharCallback`, and `SetCharacterModsCallback` to `SetCharModsCallback`. Updating is easy thanks to static type checking, and can be automated with `gofmt`:

	gofmt -w -r 'x.SetCharacterCallback -> x.SetCharCallback' *.go
	gofmt -w -r 'x.SetCharacterModsCallback -> x.SetCharModsCallback' *.go

Closes #105.

 The revision of GLFW C library used is listed in [GLFW_C_REVISION.txt](GLFW_C_REVISION.txt) file.
 
+* Method <code>window.SetCharacterCallback</code> renamed to <code>window.SetCharCallback</code>.
+* Method <code>window.SetCharacterModsCallback</code> renamed to <code>window.SetCharModsCallback</code>.
 * Added `Floating` and `AutoIconify` window hints.
 * Easy `go get` installation (GLFW source code included in-repo and compiled in so you don't have to build GLFW on your own first and you don't have to distribute shared libraries).
 * <code>SetErrorCallback</code> This function is removed. The callback is now set internally. Functions return an error with corresponding code and description (do a type assertion to GlfwError for accessing the variables).
