* Added a link-making function.
* Debugged the formatting methods.
* Improved the layout (button CSS).
* Debugged the 'load' and 'dump' functions to respect the
fragment-based structure.
* Started integrated the copy-paste function.

TODO:

* Finish the copy-pasting method (does not work in combination
with the other methods so far).
* Improve the fragment model.
* Refactor the code (it is becoming messy and ugly).
