Slash counts as a valid prefix if it comes rights before another lexeme

[ZeroBone]

The following is probably a minor bug in the lexer implementation.
The continue statement

Grammax/src/main/java/net/zerobone/grammax/lexer/Lexer.java

Line 94 in 5e7f11d

continue;

should probably be removed. For example, if an the end of the file there are slashes, the lexer will delete them leading to the acceptance of a syntactically incorrect file as correct.
