Skip tasks withtou file information in build issue view when going
back/forward.

This plugin enables loading of .tasks files into the Build Isssue list. This
is really nice if you need to e.g. browse results from static codecheckers
in creator.

Tasks files are simple tab-separated lists of one of the following forms:
description
type\tdesciption
file\ttype\description
file\tline\ttype\tdescription

The strings may contain escape codes:
\n for newline,
\t for tab
and \\ for a backslash

Make GitClient::synchronousGit use the process environment.

Windows: Add a setting to fake a 'HOME' environment variable
(%HOMEDRIVE%%HOMEPATH%) to make msysgit look for its SSH-keys
there not only when run from git bash, but also from Qt Creator.
Useful in MinGw-setups, where git must not be in the path.

updateUses() is already called after each text change.

We have no way to know when the client is actually opening its ports,
so we wait until we are reasonably sure it's done.
This is not 100% safe, but should generally suffice.
(The UTFS server seems to have this logic already built in, but it does
not seem to work on Mac.)

This will help us diagnose errors.

* If possible, create LookupContexts through SemanticInfo; it caches the
  linked Context and will be faster.
* Contexts now own their Engine.

Access to the users private resource path (derived from the
settings path) has been used in quite some places, so it's
worth moving it to the core interface centrally.

- Removed the "cpp/" dir
- Moved main.cpp and symbianicon.svg next to the main .pro.
  This also reduces the dir depth in the project view.
- Introduced "qmlapplicationviewer/" dir, which will contain the files
  which the user should not modify. All the files there have the base
  name "qmlapplicationviewer"
- Moved/renamed "qmlapplication.pri" to
  "qmlapplicationviewer/qmlapplicationviewer.pri"
