several versions of TOL in RMTPS

[Jorge]

RemoteTOL should deal with differents versions of TOL, this means changing the API of RemoteTOL and include in rmtps.conf more than one tolsh sections.

[Jorge]

• multiple tolsh sections will be possible

• projects can specify which tol version should use through key tolversion

[Jorge]

(In [1828]) fix #817 :

• load_conf clears configuratio and prints messages about initialization.

• multiple tolsh sections can be defined, the name of the section is the version of tol, include a key in order to indicate the default tolsh version

• project secctions can specify: tolversion (indicating the tolsh to use), textvar (define a general Text variable to be evaluated at boot time), pathvar (define a text variable with a path contents, the path can be absolute or relative tho the current project or other project listed in rmtps.conf). There can be multiple textvar and pathvar.

• ps_runtol is now aware of the new options.
