Made package not-playable

Added AppendChar functionality, appends a single character (designed to be called frequently, frequent calls to SetText are inefficient)

Added arrows and bullet points:
arrows can be created with \l,\r,\u,\d
empty and filled bullet points with \b and \f

Additionally to the "\n" string, a newline can now be created with '\n' character

Scaled characters by 0.4 from 0.5x0.72 to 0.2x0.288
