Local fix

Problem summary

• When using the javascript editor writing an in-line regular
  expression, which has a single quote, a validation error will be
  displayed when this in fact is a legal regular expression.
  
  USER AFFECTED:
  Business Process Manager Advanced, Standard, and Express
  authoring user who is writing javascript code in Process
  Designer, and is using in-line regular expressions which have a
  single quote character (ie. /'/g)
  
  PROBLEM DETAILED DESCRIPTION:
  The root cause here was the Javascript editor parser did not
  account for regular expressions and instead parsed tokens
  without any prior knowledge of a regular expression existing. To
  determine if some code was a regular expression the second pass
  of the parser, which builds the grammar, would attempt to
  decide. Unfortunately, in cases with a single quote character (a
  legal regex) the parser attempted to parse the token as a string
  rather than a regex.
  
  IS A WORKAROUND AVAILABLE? (Y/N) IF Y: EXPLAIN IT.
  New up a regular expression instead of defining one in-line. ie.
  use new RegExp("'", "g") rather than /'/g
  
  PROBLEM CONCLUSION:
  Need to properly support the parsing of regular expression
  tokens. This way there is no confusion between single quote
  characters in a regular expression or a single quote character
  denoting the start of a string.
  
  FIX AVAILABILITY:
  Fix for 8.0.1 is planned for next cumulative maintenace
  deliverable.
  
  Fix for 8.5 is planned for next cumulative maintenace
  deliverable.
