Merge pull request #16 from dsanz/improvements

Improvements
fix definition of "untranslated value"
improve performance by reading all target_f cells in a single operation, treating the pootle store table as any other localization file from now on. This reduces the number of mysql invocations from n*p to p (being n the number of keys and p the number of projects)
make sure we get the value from the array for comparison (not sure if real improvement nor perf penalty)
fix for non-inclusion of version api
fix bug when calling pootle export api. Try a new, quicker way of getting values from array T, saving one access
add curl debugging line, commented out by default
add overriding translation files
Make sure we check for export branch before creating it
fix dependency typo
fix unnecessary commits when branch does not change
fix git commit invocation
fix to avoid posting untranslated strings, skip commented lines, improve some log formatting
