Proposal: refactor logging, capture for dashboard recordings, output to file, serialize browser console logs

More comprehensive proposal is needed but summary is this:

• Refactor existing debug / log implementation
• Create logger wrapper utility to manage all logic
• Route debug, console.log and performance data through this utility
• Enable silencing all node based console.log per https://github.com/cypress-io/cypress/issues/2071
• Capture browser console methods per https://github.com/cypress-io/cypress/issues/700
• Write all logs to an output.log per project in AppData
• Persist logs on recorded dashboard runs
• Enable changing the logs folder via some CLI flag like --logs-folder=/path/to/logs
• Fix morgan output always appearing
• Expose a pluginEvent for internal:log perhaps
• Start capturing performance related data in logs
