Merge tag '0.11' into develop

Adjusted to sqlpp11 0.18
Fixed usage of wrong_t
Check result of binding parameters, add sqlite_reset before binding

Thanks to dirkvdb for reporting the problem.
Adjusted a few exception texts and debug messages
Added call operator to connection and adapted test to use it
Added SQLITE_ROW to the accepted return values for slite3_step
Fixed CMakeLists.txt for better out-of-source support
Prefixed names of test targets to allow usage as submodules

Previously, there were conflicts with sqlpp11 test targets which had the
same names
Minor adjustments to CMakeLists.txt
Fixed select execution and added some tests

The first line was effectively skipped due to double execution of
sqlite3_step.
Allow ROW results for execute statements

Added comment to remember what the status it is good for here
Added several select tests, counting result rows
Minor test adjustment
Merge branch 'release/0.12'
