Update troubleshooting.md

I never thought of looking in the aliases section of the documentation...
Extended the fetchFile() method of the ComposerRepository class to be
able to deal with http basic auth. In case the remote resource responds
with a 401 ask the user for access credentials and retry quering the
resource again.
Moved 401 handling from ComposerRepository to RemoteFilesystem and
displaying the url when asking for the credentials.
Reverted the last changes. Changed logic in callbackGet() method to
respect the 401 handling also if STREAM_NOTIFY_FAILURE fires as on my
local machine the handling of STREAM_NOTIFY_AUTH_REQUIRED never got
executed.

Travis using PHPUnit version from require-dev

in order not to use system version of PHPUnit and have unexpected bugs - it could be better to invoke PHPUnit from development dependencies

removing xdebug extension

Travis using PHPUnit version from require-dev
Initial feature-dist

 * extends BaseDumper, implements interface
 * put $keys into BaseDumper

 * WIP WIP WIP WIP
 * BaseDumper for utilities
 * interface to enforce 'dump()'
 * feature:
   * supports git
   * supports zip output
   * basic test to cover feature

 * add @todo for later
 * add vendor namespace to package name

 * add extension to getFilename() so we don't need to switch in there (HT, @naderman)

 * add extension (obviously 'zip' in ZipDumper)

 * create archive in destination dir (provided by __construct())

 * condensed ZipDumper
 * moved code to BaseDumper (hopefully easier re-use)

 * use ProcessExecutor from BaseDumper

 * fix assignments in __construct()
 * allow injection of ProcessExecutor

 * fix parameters

 * fix regex

 * write in 'system temp dir'
 * update test case (oh look, a duplicate regex)

 * move working directory related to BaseDumper

 * add quotes

 * place holder for these methods

 * use PharData to create zip/tar when necessary

 * add placeholder calls
 * add call to package() using PharData

 * finish downloadHg(), downloadSvn()

 * put to use

 * make BaseDumper abstract (to force extension)
 * make BaseDumper implement Interface (makes for less code in the implementation)

new functionality for dumping as .tar.gz

tar instead of tar.gz, new abstract dumpertest class

creates a local git repo instead of fetching a remote one

more oo-ish version of it

no constructor

 * refactor tests to be less linux-specific (used Composer\Util to wrap calls)

 * make filename only the version

 * various cs fixes (idention, tabs/spaces, doc blocks, etc.)
 * fixed a typo'd exception name

 * refactored downloading:
   * removed download*() methods
   * added dep on Composer\Factory to setup a DownloadManager instance

 * update CS with feedback from @stof

 * ArrayDumper doesn't extend BaseDumper anymore (hence no conflict on the interface)
 * move keys from BaseDumper back to ArrayDumper
 * interface now declares dump() to always return void

Apparently I had to update the lock.

CS fixes (tabs for spaces)
Bugfix: sprintf() was missing.

Fix docblock for @stof. ;)

Pull in lock from master.

Update lock one more time (hope it still merges).

Revert ArrayDumper static keys
Moved archive Dumpers into its own Archiver package
