As a user, I can see choose a column in Test Runs to show number of created defects in that Test Run

Whenever showing a list of Test Runs (e.g. in a Test Execution), it should be possible to select a new column "#RunDef" that shows the number of defects created only in the context of that Test Run (either in steps or globally).
By clicking on the defect count, the user should be redirected to the JIRA issue search screen with the keys of the defects filled out.

Note:
The current "#Def" available column for Test Runs shows a number of defects linked with the Test, as detailed in http://confluence.xpand-addons.com/display/XRAY/Defects+count.

Another option should be to have the Linked Test Run Defects. So instead of a single #RunDef column, like so:

Include also a column with the direct links to the issues, like so:
