Adapted my Makefile target to allow building of QT5 gui.

Inserted empty lines.

Fixed AM_CPPFLAGS in qt5 gui.

Added .gitignore.

Added some more files to .gitignore.

Updated cmake config files

Now targets are used which makes the usage even easier. Version
checking was improved. Backwards compatibility is ensured.

Added gui frontend for Qt 5

It is based on the Qt 4 gui. Mainly it replaced all occurences of "4" by "5".

Typemaker2 now also writes APIDOC.

Will probably switch to member grouping.

Prepared release 4.15.2beta

No longer use gnutls_protocol_set_priority().

Prepared release 4.15.1beta.

TLS: Introduced preprocessor variable "GWEN_TLS_USE_OLD_CODE".

If this variable is defined the old code for TLS cipher selection is
used, otherwise the new code is chosen.

The default setting is currenty to use the new code, that works at
least with the NetBank server.

Prepared Gwenhywfar 4.15.0.

Added tests for GWEN_PARAM.

Fixed a typo.

Modified XML structure use when reading and witing param values.

GWEN_Param_List_WriteValuesToXml() and GWEN_Param_List_ReadValuesFromXml() now
read/write a more compact XML tree.

Improved GWEN_XMLNode_GetCharValue() and GWEN_XMLNode_SetCharValue().

If "name" is empty data nodes will be read/written directly below the
given node.

Improved GWEN_PARAMS.

Now we can read and write lists of GWEN_PARAMs. It is now also possible to
read and write values of params only.

Also added API documentation.

make it possible to reproduce byte-for-byte identical binary packages from a
given source. https://wiki.debian.org/ReproducibleBuilds

The contents of listdoc.h is generated by the output of "find include -name...

mklistdoc: Fix minor typo

Prepared release 4.14.0.

Fix segfault on windows when using HBCI with keyfile.

Reported by hbrunn on

Major speedup of GWEN_Directory_GetMatchingFilesRecursively().

Don't check for duplicates when adding files or folders to the file/folder
list. There should be no duplicate entries anyway inside a folder.
