Release 1.0.26

Improve argument parsing in TextCommandHandler.cs

Refactor the argument parsing logic in TextCommandHandler.cs to
use a List<string> for collecting arguments and a string for
building the current argument. This new implementation correctly
handles quoted arguments by checking if a part starts and ends
with a quote, or if it starts or ends with a quote and continues
to build the argument until the closing quote is found. It also
trims the quotes from the arguments and filters out any empty or
whitespace-only arguments.
