* std.algorithm: Changed the map() function so that it deduces the return type

Browse source 
* std.contracts: Added file and line information to enforce. Added errnoEnforce that reads and formats a message according to errno. Added corresponding ErrnoException class.

* std.encoding: For now commented out std.encoding.to. 

* std.file: Fixed bug 2065

* std.format: Fixed bug in raw write for arrays

* std.getopt: Added new option stopOnFirstNonOption. Also automatically expand dubious option groups with embedded in them (useful for shebang scripts)

* std.math: improved integral powers

* std.md5: Improved signature of sum so it takes multiple arrays. Added getDigestString.

* std.path: changed signatures of test functions from bool to int. Implemented rel2abs for Windows. Improved join so that it accepts multiple paths. Got rid of some gotos with the help of scope statements.

* std.process: added getenv and setenv. Improved system() so it returns the exit code correctly on Linux.

* std.random: added the dice function - a handy (possibly biased) dice.

* std.file: added support for opening large files (not yet tested)

* std.utf: added the codeLength function. Got rid of some gotos.
