Issue 91

This reverts commit 4ab8d60642141a4b8d495747b932f7d7d9cc495a.

This reverts commit 015c7c76d4b98c0b991c062eb47493ade2f94bae.

This partially reverts 4ab8d60.

Use as in
```
for ii in cpp other tex; do addheader.py --cfg=.pylicense-${ii}.cfg .; done
```

all ranks previosuly created an ofstream object for it w/o anybody but
rank 0 ever touching it

also fix default max for intel's MIC platform

For some reason cmake errored out if Likwid was not found on that
platform.

Before the change, the DIR was set to 'g++-4.9__wo_' for each compiler. This should fix this...

The first change is required to allow for
```
Configuration(std::string key, bool value)
```
calls, and the second one is required for
```
Configuration(std::vector<std::string> keys, std::vector<long int> values)
```

[common.configuration] drop obsolete ctor

*sigh*
