Allow commit id's to be used in Compare view (BB-13957)

Currently I have to compare two branches and then fill in the commit id's in the URL, according to this pattern:

{{https://bitbucket.org/

{organization}

/

{project}

/branches/compare/

{commit-id-1}

%0D

{commit-id-2}

}}

That works but why can't I just input the commit id's in the text boxes? Seems like a simple change to me.
