Changing font size of the add/remove skipped classes button to 18sp
Creating a selector for the subject card drawable so that it presents a
different color when the user presses it (to give an idea you can hold to
see the context menu).
Creating a SpringInterpolator to run an animation allowing a custom
initial velocity for each time the animation is going to be run.
Creating VerticalScrollView so that we can not intercept touch events when
the user is scrolling horizontally.
Configuring animators on the LinMateria view on a separate method instead
of the constructor to keep the constructor cleaner.
Creating a swipe action where you can swipe the subject view out to open a
dialog to delete the subject from your list.
Also animating the alpha of the subject card when animating its
translation. Not creating tons of animators anymore, using the animateTo
and animateToDelayed (new, but nothing much) methods of them.
Gixing .gitignore to include IntelliJ project files as well (those that don't
change randomly).
 - Created a better structure of packages with mocos.data and mocos.views.
 - Changed name of WelcomeActivity to AbsenceActivity.
 - Fixed many good code practices violations (described below) for the
   mocos.data package.

The good code practices mentioned above (and that will be adopted on next
commits are):
	- Correct spacing and lines between statemnts, methods, etc.
	- Creating a convention for names of private fields: m* (all pvt fields
	  starting with a lower case m)
	- One field declaration per line
	- Never exceeding the 100 characters line barrier
	- New line in end of file
	- Encapsulation of fields
Adopting code conventions described also on the mocos.animation package.
Applying code conventions described on the mocos.view package.
Applying code conventions to the classes on the mocos package.
Optimizing imports for all files.
Translating class and field names to English.
