Now IPC is used only for some transports, which are disabled for a
packaged application. So now electron-log works using almost the same
way in the main and renderer processes. The reason - IPC is pretty slow
and can freeze an application when there are a lot of calls.
File transport doesn't use stream.Writable anymore.
New feature: hooks.
New feature: log file clearing.
New feature: colors support.
New feature: errors catching.
Changed default format option for console transport.
