Add 'forceCursor' to showCursor function

[Allerek]

Is your feature request related to a problem? Please describe.
Yes, for now showCursor is resource-dependent, that means - if we have enabled cursor in one resource, and try to disable it in another one it simply just wont work as MTA will detect that cursor was earlier requested by another resource. This can sometimes lead to problems when user is stuck with the cursor on screen, and can't do nothing but reconnect.

Describe the solution you'd like
New argument to showCursor function called forceCursor, which will skip checking if showCursor was requested by another resource, and force cursor to enable/disable anyways.

Describe alternatives you've considered
Just remove dependency?
