Ralf Becker 486a32e86d Refractured eTemplate to use:
- the etemplate_request object which stores the request data in the
  a) session (as before) or
  b) compressed and encrypted in the form transmitted to the user
  Benefit of b) is that the session does not grow and the form can
  be submitted as long as the session exists, as we need no garbadge
  collection. Of cause more data needs to be submitt between
  browser and webserver. b) is choosen automatic if mcrypt and
  gzcompress are available, but can be turned off via setting
  etemplate_request::$request_class = 'etemplate_request_session';
- static class variables instead of the before used global ones
--> This new version of eTemplate is fully backward compatible with 1.6!

/**
* allows a few variables (eg. row-number) to be used in field-names

* of "Row$row[length]" will expand to 'Row' as $row is scalar, you need to use
* "Row${row}[length]" instead. Only one indirection is allowd in a string by php !!!
* Out of that reason we have now the variable $row_cont, which is $cont[$row] too.
* Attention !!!
* Using only number as index in field-names causes a lot trouble, as depending
* on the variable type (which php determines itself) you used filling and later
* accessing the array it can by the index or the key of an array element.
* To make it short and clear, use "Row$row" or "$col$row" not "$row" or "$row$col" !!!
*
* @param sring $name the name to expand
* @param int $c is the column index starting with 0 (if you have row-headers, data-cells start at 1)

* @param int $c_ is the value of the previous template-inclusion,
* eg. the column-headers in the eTemplate-editor are templates itself,
* to show the column-name in the header you can not use $col as it will
* be constant as it is always the same col in the header-template,
* what you want is the value of the previous template-inclusion.
* @param int $row_ is the value of the previous template-inclusion,
* @param array $cont content of the template, you might use it to generate button-names with id values in it:
* "del[$cont[id]]" expands to "del[123]" if $cont = array('id' => 123)

* Checks if we have an row- or column autorepeat and sets the indexes for $content, etc.
*
* Autorepeat is important to allow a variable numer of rows or cols, eg. for a list.
* The eTemplate has only one (have to be the last) row or column, which gets
* automaticaly repeated as long as content is availible. To check this the content
* has to be in an sub-array of content. The index / subscript into content is
* determined by the content of size for templates or name for regular fields.
* An autorepeat is defined by an index which contains variables to expand.
* (vor variable expansion in names see expand_names). Usually I use the keys
* $row: 0, 1, 2, 3, ... for only rows, $col: '@', 'A', 'B', 'C', ... for only cols or
* $col$row: '@0','A0',... '@1','A1','B1',... '@2','A2','B2',... for both rows and cells.
* In general everything expand_names can generate is ok - see there.
* As you usually have col- and row-headers, data-cells start with '1' or 'A' !!!
*
* @param array $cell with data of cell: name, type, size, ...
* @param int $c,$r col/row index starting from 0
* @param string &$idx returns the index in $content and $readonlys (NOT $sel_options !!!)
* @param string &$idx_cname returns the basename for the form-name: is $idx if only one value
* (no ',') is given in size (name (not template-fields) are always only one value)
* @param boolean $check_col to check for col- or row-autorepeat
