Smart Defrag

What's new in this version:

New features:
- Text components: Added a "Key listener" script property that is executed each time a key is pressed. The "text" parameter contains the modified text unlike for the "Key validator" expression.
- It is now possible to use installer variables with array values in the arguments for launchers. Empty array elements are omitted.

API changes:
- Added a version of com.install4j.api.windows.WinFileSystem#createShellLink with a parameter of type "ShowCommand" that allows you to open a link with maximized or minimized window state

Bugs fixed:
- "Single radio button" form component: If all radio buttons in a group were disabled, an exception was thrown in console mode
- "Single radio button" form component: In console mode, the selection script of the first radio button in the group was executed and not the one of the selected radio button
- "Load a response file" action: Non-string variables were not registered automatically as response file variables again and the "Overwrite strategy" did not work for them
- "Label" form component: & characters followed by a non-space character were not shown
- "Execute SQL script" action: Non-standard statement delimiters did not work
- Installation directory selector: Several settings were not respected in console mode
- PDF action and screen produced a file named error.log next to the installer
- Unix service launchers: Not all possible arguments were reported in the "usage" message
- Unix service launchers: More robust implementation for stopping the service
- Unix launchers: Use exec where possible to replace the shell script process with the java process
- Unix launchers: JRE search sequence entries that start with $ or ~ were interpreted as relative files
- Windows launchers: The current directory was appended to the end of the class path
- Mac OS X: Running process check did not work for single bundle installer
- Mac OS X: Installers did not pump stdin
- Mac OS X: Console and unattended mode were not set to headless for the Oracle JRE
- i18n: Single apostrophes were doubled in formatted messages
- Adding imports to the static members script marked the same imports in all other scripts as unused and broke auto-import and test compilation
- For wildcard classpath entries of type "archive", the shortest available match is now used
