Teamcity stats are incomplete

[idonman]

For code coverage summary (with diffs from previous build) to appear in overview tab,
the following stats must be sent:

a) Lines or Classes
b) Blocks
c) Statements or Methods.

As per current code

Only statements stats are being sent:

    log.info(statsKeyValue("CodeCoverageAbsSCovered", coverage.invokedStatementCount))
    log.info(statsKeyValue("CodeCoverageAbsSTotal", coverage.statementCount))

But blocks are sent as custom stat:
CodeCoverageBranch

So, 2 stats are missing at the moment:

1. Block coverage stats must be sent as:

##teamcity[buildStatisticValue key='CodeCoverageB' value=' <value>'] 
##teamcity[buildStatisticValue key='CodeCoverageAbsBCovered' value='<value>']
##teamcity[buildStatisticValue key='CodeCoverageAbsBTotal' value='<value>']

2. Lines or Classes. Lines can be excluded, in favor of statements stats. Thus classes total coverage must be calculated and sent, so that teamcity coverage summary could appear on build overview tab:

##teamcity[buildStatisticValue key='CodeCoverageC' value='<value>']
##teamcity[buildStatisticValue key='CodeCoverageAbsCCovered' value='<value>']
##teamcity[buildStatisticValue key='CodeCoverageAbsCTotal' value='<value>']
