Fix opening new tab in already runned TBB

[komachi]

You should always pass -allow-remote. Otherwise new tab will work only if you pass some URL(s) on the first run.

I noticed this after using for a bit -- thanks for the PR!

I don't really understand this pull request:

but let me start from the beginning: so torbrowser-launcher 0.1.7 is in debian jessie currently, but 0.1.8 is needed for the new signing key. 0.1.8 looked suitable for jessie except for maybe de13483 which actually fixes this pull request #155 (according to the git commit message) - but then 0.1.9 came out, fixing that very commit with 3f1146e. so now i've build 0.1.9 locally with these two commits reverted and if i click on a link with middle mousebutton, it still opens in a new tab ?!?

This is on Debian, with iceweasel installed (but not running).

@h01ger It was not about middle mousebutton. Without this commit, if you run torbrowser-launcher and then torbrowser-launcher "https://github.com", you'll get popup says TBB already open. This commit fix it, so torbrowser-launcher "https://github.com" opens GitHub in a new tab of already launched TBB. The problem with -allow-remote in #157 is that if you have Firefox (not Iceweasel) installed, for some reason it opens tab in Firefox instead of TBB. It's a bug in upsteam. they should add some build flags.
