All static memory allocations were turned into dynamical ones.

All static memory allocations were turned into dynamical ones.
Improved configuration parameters:
- FifoPath	to specify the fifo path (if absent, a built in replacement is used)
- FifoBufSize	to specify the size of the internal buffer (this parameter is optional as
		the plugin will try to match the number of display columns; if it fails and
		no FifoBufSize parameter is supplied then a built in replacement is used)
Simplified and rationalized init and exit functions:
most global variables have been localized.
Fixed several off-by-one overflows memory bugs.
