v1.1

Version 1.1:

* Added resources file.
* Added window to find old calls (needs to be improved, e.g, make a
  chart on it).
* Update button on call details will only be shown if we're seeing
  today's calls. It has no sense otherwise.
* Added about Qt to menu.
* Added tooltip to tell us how many calls we've registered on the
  current week.

v1.0

Version 1.0:

* Added translations to es_ES and es_DO.
* Fixed some typos in translations and making some string literals able
  to be translated by using tr() on them.
* Incomplete labels when they're translated, fixed.
* Fixed a little bug if we have 1 call saved on the DB, it didn't use to
  be shown.
* resizeEvent of main window was refactored. I made this an internal
  class not to polute the main window class itself.
* Shortcuts are fairly modified when we're under Spanish systems.
* When saving calls instead of asking for keys() we're now iterating
  over all its values and then retrieving that value's associated key
  because we used to allocate an unnecessary container.

v0.8

Version 0.8:

* Minor changes when showing day name in CallDetails.
* Loading translation files from 'translations' folder instead of i18n
  resource. (Will be changed later.)
* Main window is now able to resize properly (is going to be refactored
  later, though).

v0.7

Version 0.7:

* Improved translations to Spanish.
* CallDetails window is now able to resize properly.
* When hovering, if it's today main label will be set to bold.

v0.6

Version 0.6:

* Added call details window to show details about what time a call was
  registered at.
* Fixed bug when showing bars about weekly registered calls.
* We're now using Widget::update() instead of QWidget::repaint() to let
  Qt optimize refreshes.
* Optimized the way of saving calls. Now we just save unsaved calls
  instead of all of them.

v0.2

Version 0.2. See changelog on commit 3e5288b.

v0.1

This is the first release. You can use it as it is already.
However, I'm working on adding some other interesting features in the future.
