python script to generate the icon include file

When a Help page call a missing icon in the icon theme set, a replacement icon must be available.

The list of replacement icons exist in core/icon-theme/<theme>/links.txt. This list is updated each time an icon is added or deleted.

The list must also be used in the Help pages build phase, where missing icons must be replaced with the right icon from the list above.

The current approach is to generate a XSL transform and include it in the main XSL transform online_transform.xsl. The auxiliary XSL is named helpcontent2/help3xsl/links.txt.xsl

The Python script attached here generates link.xtx.xsl based on the link.txt of the colibre icon theme. However the script is not inserted in the build system in CustomTarget_html.mk

The task is to add the script in the build process or, do an equivalent shell script, to produce links.txt.xsl.

That way, it will prevent to update manually list.txt.xsl and update it in git.

Notes:
1) The list.txt.xsl transform is included in online_transform.xsl
2) the xsl:include href= attribute cannot be computed by xsltproc v.1.0 and must be statically defined. 
3) usually the intermediate files are placed in workdir/ folder. However, the workdir path is a LibreOffice build parameter. It cannot be used to define the xsl:include href=
