[fingerterm] Install QML files, icons and data under /usr/share/fingerterm instead of using resources.

Changing layout with caps lock on lead to caps staying on, no way to
turn off.

Used to be done by Qt-components.

Used for all kinds of notifications

Still three instances left. Should be a Qt bug by creating warnings
before all the properties are evaluated, though.

Window size is used for pixel ratio. Shouldn't ever reach 0.

Avoiding setting default values to properties, grouped code a bit better.

Hardly see any use, operating system should offer method for
minimizing applications.

-Remove support for Maemo, Meego, Harmattan & Symbian.
-Allow definition of font for QMake.

Use text from keyEvent for capslock and basic cyrillic text support.
Added modifiers for arrows, editing keys, backspace tab
and enter. Added Insert and F1-F12.
Cleaned up the parsing, removed some useless toLatin1()
usage.
