Empty else clauses; Redeclared variables; Unusued variables

We ran Multilingual through a series of static code checkers. A few minor items were pointed out that seemed worthy of bringing to your attention. None of these are likely to cause major problems.

Empty else clauses (2):

• multilingual.js, line 228
• multilingual_survey.js, line 659

Redeclared variables (20), not listing all of these, but as an example:

• multilingual_setup.js, line 215, var_id

Unused variables (11):
multilingual.js
Line 186, counter

multilingual_pdf.js
Line 16, lang
Line 24, lang

multilingual_setup.js
line 7, setup
line 8, settings

multilingual_survey.js
line 7, project_id
line 403, showSymbols
line 594, counter

multilingual_survey_return.js
line 6, project_id
line 9, totalLanguages
line 234, setNormalCookie

I appreciate this. This thing has been through so many iterations from a plugin to module. I need to set aside time to clean it up when I can.
