Add support for #string

[ruppde]

Hello,

would be great to have support for hoovering over #string (number of occurrence) next to $string.

Hello and thanks for the report. This looks like an issue with YLS itself, AFAIK this should be already supported by YARI. A workaround you can try if you want to evaluate #string is to visually select #string in the condition section.
