Now all names in basctl are in namespace 'basctl'.
There were lots of names that included the word 'Basic' or 'BasicIDE' in
it, e.g. BasicIDEData, BasicDocumentEntry, BasicTreeListBox,
BasicIDEModule, IDEBaseWindow etc. This information is now stored in the
namespace name, so the names could be shortened: basctl::DocumentEntry,
basctl::TreeListBox, basctl::Module, basctl::BaseWindow etc.
Some other minor changes:
* LibInfos, LibInfoItem, LibInfoKey ->
  LibInfos, LibInfos::Item, LibInfos::Key
* The header guards are now uniformly BASCTL_FILENAME_HXX, instead of
  e.g. _FILENAME_HXX, which is undefined behaviour because of the '_'.
* namespace BasicIDE, BasicIDEGlobals, basicide -> namespace basctl
* BASICIDE_TYPE_MODULE, ... -> basctl::TYPE_MODULE, ...
