Rename main Module Term to less used Termin

There is a problem when using gem TConsole (https://github.com/gma/tconsole). When used in a project class or module called *Term*. TConsole takes him for a module that is in the gem *term-ansicolor*. As a result, it happens that without renaming modules or classes in the project testing use the TConsole is impossible. 

To solve this problem frequently used *Term* was replaced by the *Termin*.
