fix: ignore comment lines when reading yacy.conf keys in startYACY.sh (#736)

Previously grep matched commented-out keys like '#javastart_Xmx=512m'
alongside the active one, causing invalid JVM args and a cryptic
'Error: Could not find or load main class' failure on Docker start.

All three conf key reads (javastart_Xmx, javastart_priority, port)
now pipe through 'grep -v '^\s*#'' before key-matching.
