* Update ISSUE_TEMPLATE.md
with wiki link and minor formatting changes
* Update PULL_REQUEST_TEMPLATE.md
making the formatting more similar to the issue template, simplifying some language and improving links
It feels like the template for reporting bugs is a bit redundant - we have summary, steps to reproduce, observed behaviour AND expected behaviour, which all are very similar. I think that by paring it down to the essentials, people will be less likely to skip steps.
