Don't mess up the original structure of the generic project file list by
reconverting all the paths to be relative from the project directory.
This allows whitespace or absolute paths to be preserved even when
adding/removing files through Qt Creator.

SymbianDeviceManager needs to initialize when friendlyName is requested.

Fixed the insertion of matching braces when the token at the left of the cursor is a string literal.

- match just the spec name without a possible path
- resolve the default spec

unfortunately, the efforts to use only absolute paths internally became
externally visible ...

This is for disabling behavios in Bauhaus

Since the target names are translated, we cannot use the saved
display name from the user file.

 * This is necessary as the decission on whether Symbian support
   is available at all depends on the ToolChain used to build.
   We should improve this!

When a PP line ended with a \ (join line) and the next line was empty
(ending th joining), the following token would be incorrectly marked as
joined.

previously, the entire value hash was simply pushed on a stack upon
entering a custom function. the problem with that was that setting the
function's argument already detached (i.e., copied) the entire hash.
so instead store only actually modified values in nested scopes and let
lookups cascade to parent scopes.

improvement: 2% for qt, 15% for creator ...

it is extremely unlikely that a function would change one of the
interesting variables (all types of source file lists) but not re-export
them subsequently. thus the scoping only complicates matters and burns
cpu cycles.

we ignore the tiny possibility that this could illegitimately reset a
list while doing exact parsing - the subsequent cumulative parsing would
most likely catch these files again anyway.

these values do not require evaluating magic variables. the semantics
would be totally unclear anyway.

Use that for showing details about connected Symbian devices.
Also update the icon with an (not-)connected overlay icon.
Graphics design pending.
