[Linux] `dnvm list` should display installed runtimes in a reasonable order

[dougbu]

Example scrambled output of dnvm list on Linux:

Active Version              Runtime Arch Location             Alias
------ -------              ------- ---- --------             -----
  *    1.0.0-beta6-12108    mono         ~/.dnx/runtimes      default
       1.0.0-beta6-11944    mono         ~/.dnx/runtimes
       1.0.0-beta5          coreclr x64  ~/.dnx/runtimes
       1.0.0-beta5-12103    coreclr x64  ~/.dnx/runtimes

       1.0.0-beta5          mono         ~/.dnx/runtimes

Bonus points to match order used on Windows 😸

What is the desired output? Just that the versions are sorted? What is the output on Windows (I don't have a Windows box)?

Checked from @DamianEdwards presentation at NDC (https://vimeo.com/131191236#t=12m45s) and it's alphabetical ascending. Column order is Version, Runtime, Arch...

List is again unsorted on Linux, at least on a Mint 17.2 / Ubuntu 14.04 / Linux kernel 3.16 system. Example output:

$ dnvm list

Active Version              Runtime Arch OperatingSystem Alias
------ -------              ------- ---- --------------- -----
       1.0.0-beta8-15529    mono         linux/darwin    
  *    1.0.0-beta7          coreclr x64  linux           default
       1.0.0-beta8-15519    coreclr x64  linux           
       1.0.0-beta7          mono         linux/darwin    
       1.0.0-beta8-15530    mono         linux/darwin    
       1.0.0-beta8-15120    mono         linux/darwin    
       1.0.0-beta8-15530    coreclr x64  linux           
       1.0.0-beta6          mono         linux/darwin    

Have updated using dnvm.sh update-self && . ~/.dnx/dnvm/dnvm.sh to 1.0.0-beta8-15502. Script contains

for f in `echo $runtimes | sort -t. -k2 -k3 -k4 -k1`; do

but the sort isn't working.
