HTML resource templates and HTML generation code changed to ensure full paths to resources are specified.
This is a kludge to have another crack at fixing bug #75 "Floating point error in 4.4.1 (and later)" (https://sourceforge.net/p/codesnip/bugs/75/).
Not a tidy solution - whole of HTML code generation needs to be reworked.
