Valentina Studio 4+

New:
* [Report Editor] Implemented reports for MongoDB databases. The source query can be defined in JSON or JavaScript forms.
* [Report Editor] Source queries can be defined using JavaScript code. This allows JavaScript to build a set of data and produce a report.
* [Report Editor] The content of text controls (text field, expression field, label) can be printed on multiple pages if it doesn't fit on one page.
* [ValentinaDB] Deterministic levels for UDFs.
* [MongoDB] JavaScript can be used to query databases; previously, only JSON was available.
* Database Documentation Generator: a special project that produces a report with a description of all major DB objects. Based on Valentina Reports, it works for ValentinaDB, SQLite, MySQL, PostgreSQL and SQL Server.
* [FREE] version users can adjust the datasource and generate predefined reports without modifications.
* [PRO] owners can tune the .vsp project to their needs.
* Valentina Studio can now show useful tips about its features.

Improvements:
* [Data Editor][PostgreSQL] The Data Editor filter is now case-insensitive by default (similar to other engines).
* [Data Editor] Improved performance, especially for DateTime values.
* [Data Editor] The Refresh button reapplies the filter if it was applied before.
* [Schema Editor] Bookmarks are not shown in the left panel by default; this can be changed in the preferences. Bookmarks are now available in the main toolbar, in the new button with a menu.
* [Schema Editor] When you connect to a DB Server and see a list of databases, there is no need to double-click a database to open it because Valentina Studio considers all databases always opened.
* [Schema Editor] Sizes are shown in the Property Inspector as KiB, MiB, etc.
* [Schema Editor] Column View:
* On the right side of the column header, you can see the counter now.
* For Databases/Schemas, you can see two counters to easily understand how many objects are hidden.
* Each column now has “dynamic” buttons that are shown only when the mouse cursor is moved over the column header.
* Different columns may have different sets of buttons.
* Button “+” opens a dialog to create an object of the corresponding type.
* Button “Search” - displays the SEARCH-FILTER in the column header.
* Button “Options” - displays a dialog where you can choose which Database/Schema to display and which to hide.
* [SQL Editor] 'Default Schemas' menu choices are saved to prefs and restored on the next start.
* [SQL Editor] Implemented background reloading of identifiers when needed.
* [SQL Editor] Ident Resolver now recognizes Valentina Report parameters $P() and $P!().
* [SQL Editor] Ident Resolver - PostgreSQL-style of type-casting 'ident::type' now is recognized. Affects PostgreSQL and ValentinaDB.
* [SQL Editor] Ident Resolver - is refreshed on changes in the 'Default Schemas' menu.
* [SQL Editor] Ident Resolver - added recognition of the query of type SELECT schema.funcName() for databases with schemas.
