#72 (tests) Beautiful colors
#75 (fixed) Import image expose too much
1. Removed imported.php - as being of not much use. Replaced  it (in step3 of install) with an updated .htaccess inside [import] folder
2. Updated import image command to use direct URL to imported image
3. Updated step3 of install to create update .htaccess file
4. Remove .htaccess from [import] and [diagrams] folder as they are generated by installation wizzard
5. Updated ignore rules for mercurial and git
