We use to write the wrong property to file, leading to a warning
in PHP 7.1 since the `switch` never matched anything and the variable
was left as a string instead of as an int.
Closes https://github.com/PHPOffice/PHPExcel/issues/1110
Removed "unescape enclosure functionality", since the unescaping is already handled by fgetcsv,
and performing the unescaping again would actually result int the text from the cell being read wrong.
As an example try parsing the folowing CSV:
```
"<img alt="""" src=""http://example.com/image.jpg"" />"
```
With the additional unescaping it would have ended up as:
```
<img alt=" src="http://example.com/image.jpg" />
```
instead of the correct:
```
<img alt="" src="http://example.com/image.jpg" />
```

Settings: deleted libxml_disable_entity_loader() calls since they're not necessary.
Prevent setLibXmlLoaderOptions() and getLibXmlLoaderOptions() to call the libxml_disable_entity_loader() function which alter the global state of libxml.

Those were deprecated a long time ago in 59932b0cac
but their replacement seems to have never been added. 5 years later the
best solution is to un-deprecate them and if someday their replacement are
actually added, then we can re-deprecate them properly.
Closes#22
Over the years PclZip became a maintenance problem. It's code base
is old and the official project seems to have died out. ZipArchive
is now more commonly available and offer an easier and more complete
API. So PclZip was dropped in order to focus our efforts on what matters.
Closes#18
We need to make note of two things:
- The old code was trying to clone an objectArray, and hence was performing a shallow copy of memoryDrawing objects (the __clone magic function was not getting invoked).
Instead, if one loops over the objectArray, and then clones the individual memory drawing objects, then the __clone function for the MemoryDrawing object is invoked.
- The __clone function for memory drawing was using the clone keyword which does not deal with circular references (Since memoryDrawing object had references to worksheet object, it was encountering an infinite loop). However, serializing and unserializing objects deals with circular references pretty well.
Fixes#92Closes#106
By design, UTF-8 allows any byte-oriented substring searching algorithm,
since the sequence of bytes for a character cannot occur anywhere else
([source](https://en.wikipedia.org/wiki/UTF-8#Advantages_3)).
So `str_replace()` also works for UTF-8-encoded strings, assuming that
the input strings are valid UTF-8 strings. The previous implementation
of mbStrReplace() did nothing to detect invalid strings.
Also, `str_replace()` does not support [Unicode equivalence](https://en.wikipedia.org/wiki/Unicode_equivalence),
but nor do the other `mb_string` functions, and nor does `=SUBSTITUTE()` in Excel
(tested on Excel for Mac version 15.19.1, Excel 2016 for Windows and LibreOffice 5.1).
Closes#109
