upgraded to
jquery 2.0.3
bootstrap 3.0.2
font awesome 4.0.3

and updated to
webshim 1.11.3
select2 3.4.5

Made lots of changes to the user interface to accommodate changes in bootstrap 3. Far more icons, layout tightened up a little.
Some backend changes, but mostly just optimisation to better fit with PRG

switched xls documentation files to xlxx, will have to experiment with git hooks to version control as something other than zipped binaries
got rid of time branch,
split branch into skip forward and backward.
skip forward is a little complex now, but hopefully can now the job of a time branch more intuitively (together with a very long explanation)
condition evaluation
tried to make run modules more intuitive by splitting branches into backward and forward and removing time branches in favour of doing time stuff in branches too.

wrote extensive examples and documentation for all modules
switched skipif to showif, hopefully avoiding double negative think

used bootstrap 3s grid model more as intended
improve documentation
Merge branch 'release/v.0.4.0'
