Add more text buffers for CLEO texts

[VitalRus95]

Currently, there's only one shared text buffer for all the types of text where CLEO can output a custom string:
https://github.com/cleolibrary/CLEO4/blob/master/source/CTextManager.cpp#L23
char message_buf[0x80];

In practice, sometimes different types can be used at the same time, either in one script or in different ones. When this occurs, every text is replaced by the last one, which can be frustrating and limiting.

What I propose is introducing individual buffers for all types of text, i.e. print, print big, print help, etc. Thanks!
