SVGHMI: add static file serving feature.

Added two buttons to add and remove files.
Files are stored in project inside a directory named "static",
itself located in svghmi CTN instance files. Exemple :
exemples/svghmi_csv_json_img_table/svghmi_0@svghmi/static/
Files are transfered as "extra_files", but with a prefix
added to their name to avoid conflics.
#!/usr/bin/env python

from lxml import etree
class XSLTransform(object):
""" a class to handle XSLT queries on project and libs """
def __init__(self, xsltpath, xsltext):
# parse and compile. "beremiz" arbitrary namespace for extensions
self.xslt = etree.XSLT(
etree.parse(
xsltpath,
etree.XMLParser()),
extensions={("beremiz", name): call for name, call in xsltext})
def transform(self, root, profile_run=False, **kwargs):
res = self.xslt(root, profile_run=profile_run, **{k: etree.XSLT.strparam(v) for k, v in kwargs.items()})
