refs #6015 hide no data in category message if search is used
refs #6413 reduce number of jobs in travis.

Not sure if this would work. We would basically only start a job for
1 x AngualarJS
1 x JavaScript
1 x All Tests with PHP 5.4 and MySQLi
3 x All tests with PDO (5.3.3, 5.5 and 5.6)
1 x Unit test with PHP 5.4 and PDO
1 x Integration test with PHP 5.4 and PDO
1 x System test with PHP 5.4 and PDO
= 9 jobs compared to about 18 before
Merge branch 'master' into 6413_reduceTravisJobs
The initSession method has not been changed

Reproduce the error: When changing the password of the user from "User settings", it throws an fatal error.

Why ? : The initSession method has not been changed in the processPasswordChange method of the UsersManager Controller class.
Missing SessionInitializer namespace
Merge pull request #6455 from burakcakirel/master

Use SessionInitializer in UsersManager.processPasswordChange since initSession method has moved from Auth to aforementioned class.
refs #6413 fix script error
Merge pull request #6456 from piwik/6015_hideNoDataMessage

Hide no data in category message if search was used
updated submodule
refs #6413 do we actually need the config param? don't think so
refs #6413 remove code coverage generation for system tests.

At least for now as mentioned in ticket it does not really make sense
to run them and they take a long time > 50 minutes.
refs #6413 execute the single test suites before AllTests so we get a faster result for them
.travis.yml file is out of date, auto-updating .travis.yml file.
refs #6413 need to adjust travis template otherwise tests wont run
Merge branch '6413_reduceTravisJobs' of github.com:piwik/piwik into 6413_reduceTravisJobs
Refs #6364, encode columns in PivotByDimension filter to ensure UTF-8 encoding. Will avoid php warning given on some PHP 5.3 builds for json_encode-ing decoded &nbsp; entities.
refs #6413 and again... we need to run PHP 5.4 first
refs #6432 should fix a possible undefined function call
Refs #6452, move remove existing notification fix to angular directive.
refs #6413 execute js/angular tests earlier as they are quick to execute. Otherwise we have to wait forever for a result
