Build Pentadactyl on Ubuntu

This builds pentadactl on Ubuntu in a simple './build-pentadactyl'. I use it since daily builds have been sporadic.

Issues

• issue 95: not working entirely correctly on firefox 42
• issue 79: signing enforcement of firefox 44 and later (warning only in 42, 43) will need to be addressed.
• issue 99: Future development of Pentadactyl

# 
# as of december 2014 there are no daily builds of pentadactyl on http://5digits.org/nightlies
# and the ones available do not support firefox at version 35.0
# so this will build pentadactyl on an ubuntu system and write
# pentadactyl-1.2pre.xpi in the directory you run it in.
# then just point firefox at that via: file:///path/to/file.xpi to install
