Reverted the requirement of PHP 5.3.4 matching Symfony's revert

Added PHP 5.3.3 to Travis as there was a BC break in PHP ~5.3.8
Took the close method out of Read/Write interfaces into its own
Updated composer files to v0.1.1 tag

[Socket] Rename connect event to connection

For the record, I disagree with this. But I will cry in my corner for this
one.

This is consistent with the nodejs naming.

* origin/master:
  [Socket] Suppress notice when binding to a port, fixes #45

Re-enabled detailed errors on buffer write errors

Removed the option for output buffer chunk size, use defaults
Removed the unit test that check specific string on error
Unit test just checks an exception was thrown on an invalid write

Added a chunkSize parameter to set the number of bytes the buffer will write at one time
The write listener will only be removed when the buffer has been emptied
Removed exception error handler:
fwrite can send data AND trigger an error, the exception destroyed the $sent variable
