Add tests for symlinked files

Fixes matthiasmullie#77

Stop testing 5.3 on Travis, it no longer supports it

Merge pull request matthiasmullie#62 from EkkoSense/master

Allow URL-rewriting without saving the minified content to the file system

Don't collapse line feeds after "return"

return is not guaranteed to be followed by a return value.
It could just be "return", followed by nothing (void return),
not even a semicolon, just line feed (ASI)
Whatever is next could, for example, be another operator.
We may just need ASI to kick in there, so keep the line feed
after return.

Fixes issue matthiasmullie#54

Fix relative target path tests

Allow minified data to be written to cache

Add gzip method

Fixed matthiasmullie#47

Don't convert standalone arrays

"return" looks like it could be a variable of which ['x']
is a key. I've improved the code to also check for keywords.
If whatever preceeds it is one of the keywords, don't convert.

Fixes issue matthiasmullie#44

Empty strings should be extracted after all

The extraction routine needs to skip that match.
However, it doesn't need a placeholder value.

Fix recursive relative path resolving

I had to split the action of minification into a separate
method because recursively importing files requires them
to also be minified, and I don't want that one to write
to a file.
