Summary of changes:

Application:
- Pressing F1 shows help, i.e. it points a web browser to the relevant part
of the user guide (in most program windows). Most dialogs also have a Help
button now.
- Translations updated: Czech, French, German, Russian, Spanish.

Libraries:
- libgwyprocess: New function to find a height threshold by the Otsu method.
- libgwyprocess: New functions to calculate data field total variation.
- libgwyprocess: Macro gwy_data_field_invalidate() is also provided as
a function so it is available in pygwy now.
- libgwymodule: New functions to obtain the name of the currently running
file, proc, volume and graph module functions.
- libgwyprocess: New functions to count regional minima and maxima.
- libgwyapp: New simplified logging functions that do not require passing the
function name.
- libgwyprocess: New function for numbering grains assuming the mask is
periodic and grains can touch across the opposite edges.
- libgwyapp: New functions for help handling.
- libgwydgets: Real scale in 3D view can be set arbitrarily, not just 1:1.
- libgwyprocess: New function to update units and dimensions of 2D FFT output.
- libgwyapp: New file module utility function for masking NaNs and infs.

Modules:
- OpenGPS (new): Imports OpenGPS surface data format (ISO 5436-2).
- JEOL JSPM (new): Imports JEOL JSPM data files.
- Diffusion synthesis (new): Artificial surface generation by a diffussion
limited aggregation simulation.
- K-means (new): K-means clustering for volume data.
- FITS (new): Imports Flexible Image Transport System images.
- FemtoScan TXT (new): Imports FemtoScan exported TXT data files.
- Filters tool: Gaussian smoothing is no longer limited to integer FWHM.
- Columnar synthesis: Can plot the evolution of some statistics during the
growth.
- APE DAX: Warning about invalid logging function name was fixed.
- NT-MDT: Fixed loading of old spectroscopy from Nanoeducator2 data.
Search of external data in another possible location is implemented.
- Pygwy: It is possible to write volume data processing modules in Python.
Brick has a duplicate() method, gwy_app_data_browser_get_current() supports
brick-related items. Python error messages are no longer silenced after
Python modules are run.
- Color range tool: The range can be set to the range of masked/unmasked
values.
- HDR image: NaNs and infinites in floating point images are removed and
masked upon import.
- Slope distribution: A bad typecast causing Gtk+ warning was fixed.
