* WIP: first attempt to fix issue-983
* WIP: bugfixes
* Fixed a problem with displaying empty cell dimensions, one warning
* Another fix: don't allow proxy cells to be selected in the instance properties dialog. This creates a confusing behaviour
* Fixed a few flaws in the cell selection scheme on the instance properties dialog.
* Early warning when trying to build a recursive hierarchy.
* Another fix: avoid too much undo in case of errors thrown during 'apply' followed by 'cancel'
* First attempt to fix issue 984
* Fixed issue-983 solution
* Fixed the modification status of PCell parameters for 'apply to all'

The problem was essentially the "specific path" which got invalid.
The solution is to establish a better criterion for "path validity"
and use for failsafes against invalid paths.
In addition, the path validation has been modified such that a
better choice is made about the remaining path after a cell gets
deleted.
1. removed some duplicate symbol linker error
2. removed many compiler warnings (mainly size_t/int compatibility)
3. consistent definition of db::pcell_id_type
4. removed UTF-8 character codes from string constants
5. float constants for float arguments
6. timeout in tlHttp when no openssl lib is found (instead of stalling
app)
