#25 Strings in gnerated equence diagrams must be escaped

[Oliver Boehm]

The logged Strings in the generated .pic file must be escaped (e.g. double quotes must bei converted to \") otherwise you'll get an error like

pic2plot:processData.pic:477: there is no variable `ecoscoreaccel'

if you try to convert it into another formet.

[Oliver Boehm]

Only the logged return value seems to be handled incorrect (escaping is missing)
