rootPath should be changed to "."

[camilovietnam]

Brief description

In the file main.go, line 44 there is a commented out line that sets rootPath to ".", and in line 43 we set it to "/data/www/go-admin-en" which is incorrect unless you are using this folder as your working directory.

It would be better if the rootPath variable was set by default to "."
