use a char32_t character as a main character when converting strings
Use a char32_t instead of a wchar_t type. This is needed on systems
where sizeof(wchar_t) is equal to 2.

add support for declared cursors
Declare a cursor with the Finder::declare_cursor() method and next get the cursor with get_cursor():
morm::Cursor<MyObject> cursor = finder.
  declare_cursor("mycursorname").
  select().
  raw("ORDER BY column_name ASC").
  get_cursor();

The cursor now can be used with fetch.*() methods and then get() or get_list():
MyObject myobject = cursor.fetch_next().get();
std::list<MyObject> myobjects = cursor.fetch_forward_count(10).get_list();

fix: correctly use a table name when using Finder::use_table_prefix(true)
We cannot use aliases in the form of "tablename"."fieldname" - now it was
changed to "tablename.fieldname".

Sample how to get the id field, assuming the table name is 'mymodel'.
mymodel = finder2.
          select(morm::Select::no_auto_generated_columns).
          use_table_prefix(true).
          raw("SELECT id AS \"mymodel.id\"").
          raw("FROM mymodel").
          raw("WHERE id = 25").
          get();

In addition, there was an error that the table name was not correctly set
for the first object in the hierarchy - it was empty, e.g. ""."field_name"

Tomasz Sowa 43dfbd5d5a add possibility of calculating how many rows there were before LIMIT was applied
The Finder has get_rows_counter() method which returns how many rows there were
before LIMIT clause was applied. The select(...) method should be called with
Select::with_rows_counter flag in such a case.

while here:
- change the semantic of Finder, now the select(...) method takes a morm::Select flags,
  and we have such flags:
  - Select::no_auto_generated_columns - do not generate columns from models
  - with_rows_counter - add an additional column for the rows counter
- remove Finder::prepare_to_select() - now use select(...) with no_auto_generated_columns flag
