Title: Modified lexer

Not sure you'll like this one. I don't really understand the purpose of the `EXCEEDING_CHARACTER_LITERAL` token.

Here are the fixes:

* Added support for type variables like `'a`, `'T`
* Corrected golden sets to make them compliant with `TYPE_VARIABLE`
token
* Deleted `EXCEEDING_CHARACTER_LITERAL` rule as it was messing the rule
for `TYPE_VARIABLE`
* Made **LexerVisualization** aware of type variables as *identifier* tokens
