Allow easy copy of binGraph diagrams from the webgui

[geekscrapy]

binGraph images are currently output as SVG. These images cannot be easily saved and shared. The proposal is to change the output to PNG. This creates a lossless image, but can be saved + shared easily.

Changes required:

• CAPE/lib/cuckoo/common/graphs/binGraph/binGraph.py

  Line 172 in 355789c

  'format': 'svg',

  > change 'format' to 'png'

• CAPE/web/analysis/views.py

  Line 852 in b772fea

  bingraph_svg_content = ""

  > mod variable name bingraph_svg_content to bingraph_png_content (and all other references)

• bingraph_png_content needs to be base64 encoded so we can load this into the webpage with minimal effort

• CAPE/web/analysis/views.py

  Line 853 in b772fea

  bingraph_svg_path = os.path.join(CUCKOO_ROOT, "storage", "analyses", str(task_id), "bingraph", "ent.svg")

  > mod variable name bingraph_svg_path to bingraph_png_path (and all other references)

• All references to graphs.bingraph.content in view templates need to be modified to display a base64 encoded image (data URI) (e.g. https://stackoverflow.com/questions/8499633/how-to-display-base64-images-in-html)
