Previously, there is nothing to separate whether the button
command is a single click or a double click. Every time we
click the shift button, it always look for the second click
and always activate the caps lock. There is no time limit to
specify if there will be a second click and always recognized
the upcoming click to activate the caps lock. The correct be-
havior of a shift button is that a single click is used to
enable the upper-case and automatically turned into lower case
when the next letter is typed. Another case, within a specific
time, if a second click comes, the caps-lock is activated and
keep the upper-case mode, otherwise the upcoming click is used
to abort the upper-case and change the keyboard mode back to
lower-case.

Unit test is also updated.

[ChangeLog] Changed behavior of shift handler to only activate
caps lock if the shift key is double-clicked.

This change adds support for smallText label in the key and also
modifies the default behavior of alternative keys.

The smallText property in the BaseKey is by default set to default
alternative key. The keyboard layout can modify the smallText if
necessary. However, the smallText is not visible by default. It can
be set to visible at KeyboardLayout, KeyboardRow, KeyboardColumn or
Key level.

Previously the alternative keys included the "parent" key as the
default highlighted item in the list. This behavior is now changed,
and the "parent" item is filtered out from the effective list presented
to user. Rationale for this is that if the smallText feature would be
turned on for existing layouts, they would render the same key label
twice.
