Buffer cell configuration in ClockTree. More config parameters in Chip. 

* New: In ClockTree plugin, select the name of the buffer cell through
    configuration (parameter: "clockTree.buffer"), and guess the I/O
    name of this buffer automatically.
      Put configuration parameters in plugin.conf and not mauka.conf.
      Bug: strangely triggers a coredump in components collection
    when used with <vsxlib>. Some debug printing still active until
    that is solved.
* New: In Chip plugin, make the size and numbers of the block rails
    configuration parameters (in plugin.conf).
