Issue Summary

Add an option to specify which Readme file to be displayed if there are more than one readme files like Readme.md and Readme.markdown

Steps to Reproduce

1. add two readme files Readme.md and Readme.markdown
2. The Readme.md is always displayed by default

Expected Results

The results are as expected no problem there.

Actual Results

The results are as expected no problem there.

But it would be nice to have an option to specify and configure which Readme file needs to be displayed

Workaround

Use README files with the same extension, but add an extra qualifier to the filename, before the file extension. For example if you add a file called README.development.md, that will be found before README.md and thus that will be the file displayed in Bitbucket Server. The syntax for this is:

README.<qualifier>.<extension>

Where <qualifier> is anything that is alphabetically before <extension>
