Clear syntax of main scripts and plugins

Fix syntax and style of standard scripts

• Follow syntax errors or warnings The editor of Tampermonkey has a syntax check utility, but it shows so much errors or warnings due to the following elements:

  • missing semicolons
  • redeclaration of variables
  • function definition in a loop
  • operands at the beginning of new lines
  • and so on Although in the most cases they are not critical issues, the many messages make debugging so difficult. Now they are fixed and the check gets clear. This would speed up the processes and the development a bit.

• Remove semicolons among main code files. No longer adding them at compile is needed.

• Change tabs into spaces and arrange indents in plugins.

I've added a commit to fix a bug that a function may overwrite the argument, whose 'var' declaration as a local variable I had removed.
