Added dialog for smooth (gaussian blur) filter which now accepts
a parameter for setting the strenth of smoothing (bluring).

Currently implemented Gaussian Blur filter uses a static matrix
which means that the filter can not be parameterized. The new
implementation of Gaussian Blur filter and accepts a blur radius
as a parameter so the user can change the strength of the blur.
For this the blur matrix is generated at each call. The new Blur
implementation reuses separable convolution from Lanzcos rescale.

For negative values of radius the Bitmap will be sharpened. For
this an Unsharpen Mask filter is used, which is actually a blurred
image substracted from the original image.

Convolution calculation now uses 2x transposing horizontal pass
instead of horizontal and vertical which simplifies the code by
reducing code duplication.

Instead of more convolution methods, only one generic method is
used and kernels are now a parameter to the method. For this
Kernel class was introduced with responsibility to calculate
kernel walues and hold kernel specific information.

Besides Lanzcos resampling also Box, Bilinear and Bicubic resampling
was introduced. Box is the simplest and fastest but with still
good quality.
