This adds app shortcuts for the most recently used cards.
When a new card is accessed, it is added to the shortcuts list.
When the list exceeds its maximum size, the least recently
used shortcut is discarded.
Android limits the maximum number of shortcuts to 5, however
it recommends in its documentation to limit this to 4. This
commit limits this to 3, however, as that is aesthetically pleasing.
By request, a project on Transifex was created to better
manage translations. To make things less confusing, instead
of using the MissingTranslations lint error, and thus needing
to add stub translations, the progress of translations is now
handled on Transifex.

This case was hit at least once by a user, though the scenario
is not known. If it is hit, post a message and bail gracefully,
until the reason can be determined.
When passing a phone to a clerk to scan the barcode, if the
phone is rotated and the screen reloads it can be bothersome
or confusion. To avoid this situation, a new option is
added to lock the screen.
A menu icon is now added which defaults as unlocked. When
touched the app sets its orientation to the "natural" orientation
of the device. When touched again the sensor dictates the
orientation of the device.
Even with passing a bundle with the layout ID sometimes
some users will encounter a situation where the _layout
variable is null. To avoid further issues, creating a
class for each intro slide, so the layout is encoded
into the class itself.
When reducing the pixel size of the width, if the height is not
scaled to match then 1D barcodes end up being squished and are
too narrow to scan. To avoid this, scale the height to match.
Then, when the barcode is loaded into a Bitmap it will scale up
to the correct size.
It was found that on a Galaxy S4 a barcode width of 400 px started
to see some blurriness, but 500 px still looked sharp. Reducing
the maximum width to 500 px.
If orientation and resize are not handled if the screen is
rotate or resized the IntroSlide fragment loses its layout,
and when it tries inflates the layout it fails to do so.
