Added JFileChooser handling

Added member variable m_dirname in which the path from the JFileChooser
gets stored (if and only if the user pressed OK)
Added try/catch for image write

Could be thrown if user has chosen a bad file name (for example :/ on
windows)

replacing long with double should avoid overflows, double max value is
x*10^134 while long only has x*10^18
Bug 4552 - Image Parameter Adjuster Node

Removed the empty string and added two horizontal glues to center the
text, flickering should now be gone (haven't seen this behavior in the
other components)
Added a nice offset

Added a nice offset to the SetThresholder, now the text stays in the
middle.
